Guyathlon 

An "event" which includes many dudes, and only one participant of the opposite sex-usually your friend's mom.

"Hey Ricky, I heard your mom came in first place in the guyathlon yesterday. High five."

Or:

"We had a guyathlon on your mother, thank you."

shirt move

During oral sex, the action of lifting one's shirt up to deposit a load onto one's own stomach.

Beats the alternative of getting it on your clean sheets or your favorite shirt.

"I knew she wouldn't swallow, so I had to pull a shirt move."
