Greg Louganis 

1- Boring Definition: Olympian Diver famed for breaking his head on the diving board and covertly leaking AIDS into the pool.

2- Cool Definition: Sexual act. Performed by engaging in intercourse and bending your partner over a coffee table or other low surface requiring them to use their arms to hold themselves up. At a climatic moment you pull their arms out from under tham causing their face to bounce off of the coffee table, must yell 'Greg Louganis!' See also Tony Danza

1- Greg Louganis was a dick head to give the pool AIDS like that.

2- Megan is so dumb. I'm totally gonna give her the Greg Louganis tonight, man.

Greg Louganis 

When toilet paper is laid across the top of the toilet water stopping the water from splashing back up and onto your butt after you poop.

I am going to head to the bathroom and drop a Greg Louganis.
