3-D was one of the three high school boys who made up Biff Tannen's gang in 1955. He got his nickname from a distinctive character trait; "3-D" was always wearing a pair of cardboard 3-D glasses with red and blue lenses, which were worn in theaters when watching 3-dimensional movies.

Back To The Future

While in Lou's Cafe, the doors fly open and in walks Biff Tannen and his friends Match, Skinhead and 3-D, who have come to harass George McFly. It turns out that Biff has been forcing George to do his homework, something George has been slacking off on. When George admits that he hasn't completed Biff's homework, figuring that it is not due until Monday, Biff gets annoyed, and raps George on the head, reminding George that he will get expelled if he hands in his homework in George's handwriting. George finally agrees to finish up Biff's work and hand it over the next day, and Biff and his friends leave.

Marty McFly tries encouraging George to talk to Lorraine Baines-McFly, however, an attempt to simply introduce them to each other fails because Lorraine is already smitten with Marty. Dr. Emmett Brown finds that the situation is more serious than they'd thought; George lacks the self-confidence to ask Lorraine out, as he fears that he couldn't handle a rejection if she said "no", and getting them together permanently could be impossible. Over lunch, Marty tries again to convince George by saying Lorraine has been talking about him and that he should ask her to the Enchantment Under the Sea Dance. George spends his lunch by himself writing science fiction short stories. Marty asks to read one of them and George refuses, saying he's afraid people would be critical. He also suggests that Lorraine may want to go with someone else to the dance, namely Biff, who we see is across the cafeteria, sitting with Lorraine and trying to grope her. Marty immediately marches over to them and pulls the much larger Biff off his mother. Biff begins pushing Marty, however, Marty, unlike his meek father, begins pushing back and is about to fight Biff when Mr. Strickland breaks it up.

The next day, George rushes up to Marty at the Texaco station, disheveled and frantic, having overslept, while Marty is trying to open a Pepsi -- George pops it open with the bottle hook on the machine. George knows he needs to ask Lorraine out but he doesn't know what he should say. Marty takes George back to Lou's Diner, where Lorraine is hanging out with her friends. Marty suggests to George that he tell Lorraine, "Destiny has brought me to you." George orders a chocolate milkshake to calm his nerves before approaching Lorraine. It gets off to a shaky start when, in a fit of nervousness, George accidentally mangles the lines Marty gave him.

Though Lorraine seems charmed by him, George's attempt comes to a grinding halt when Biff and his friends come in to toss him out. As Biff demands money from George, Marty, sitting at the counter, "accidentally" trips Biff. Biff turns his anger on Marty, and is about to punch him when Marty tricks him into looking away, giving Marty the opportunity to shove Biff and bolt out the door.

Once outside, Marty grabs a passing girl's scooter, tears off the crate and turns the bottom into a skateboard. Biff and his goons chase Marty in Biff's car around the town square. Marty is able to avoid serious injury. While riding on the hood of Biff's car, he distracts them by suddenly jumping up, jumping over the hood, the windshield and the backseat, and then hopping off onto the waiting skateboard at the rear. Biff and his friends are confused, and then see they are barreling towards a manure truck parked on the curb. They can only shout "SHIIIIT!!!!!" as the car slams into the back of the truck, which dumps its entire load of manure on them.

While inside Doc's car parked outside of the dance, Marty and Lorraine talk. Just then, the door is opened and Marty is pulled roughly from the driver's seat. But to Marty's shock, it's Biff, drunk, and seeking revenge for the $300 in damages Marty inflicted on his car in the manure truck accident. When Biff sees Lorraine in the car, however, he throws Marty to Match, Skinhead and 3D, climbs into the car, and begins to molest her. Match, Skinhead and 3D take Marty out behind the school and toss him into the open trunk of the first car they see, then slam the lid shut. Unfortunately for them, the car belongs to Marvin Berry and the Starlighters. They scare Biff's gang off and they realize that the keys are in the trunk with Marty.
