Biff Tannen 

A quick tempered, slow witted jock, often in the context of a bully. A Biff often compensates for his lack of knowledge with force or otherwise aggressive action.

The term is derived from the bully in Back to the Future I and II who harassed George McFly not only in has past, but also through the future.

A man with big hands. And an even bigger heart. Often Canadian, Tanne is a man who likes basketball.
You should be grateful if you ever come across a Tanne. But lookout, he will steal your bitches. He's a player.
All the girls simp for Tanne and his hot boy shorts. Tanne is life.

Research Tangent 

Research Tangent: digressing suddenly from one topic of discussion to run to the nearest internet source in order to thoroughly research information either to: (A) reinforce a particular point or (B) attempt to relieve oneself from ignorance. Can be either directly or indirectly relevant.

... a trend that is sweeping the nation! Because knowledge is power!
Example: She totally went off on a research tangent in the middle of a movie last night when she wasn’t sure if sodium thiopental was the same as sodium pentothal.
