Having sexual intercourse with someone while playing the bagpipes. This does not usually attract many bystanders therefore it is useful when wanting some privacy

A person who loves living in the past. The persons constantly talking about a sport they used to play and brag about how they were the greatest at it and that they could have been the best at it if they would of overcame a certain obstacle (Like breaking a bone or that they were held back by someone etc.) It's also a reference to Uncle Rico from Napoleon Dynamite
Brad: Man I could have been a top NFL prospect if I would have worked on my game more back in the day
Tim: Dude shut up you're being such an UNCLE RICO

The one uncle you have that is always drunk and slurs. This is a fellow that always wants a hug at a family get together and reeks of alcohol.

Any one being who becomes a free-loading, life-ruining, football-throwing, tupperware-selling, time-machine-buying, bust-must-plus-vending, steak-eating Bodaggit.

An Uncle Chan is the asian version of an Uncle Tom. Basically he is a lame ass fool who has no confidence or self-respect. Instead of figuring a way to be a more manly, cultured, and dope ass person, he resorts to seeking validation from the white man, which is something a lame ass bitch does. What he should be doing instead is figuring a way to be a more cool ass person by inventing something dope and useful that everybody thinks is cool. And then beating the white man at his own game!
