While jerking off a man, with the free hand you hit the tip of the cock with an open palm as if you are playing the popular carnival game "whack-a-mole".
I'm so pissed at Tommy for flirting with that fat broad at the bar. When we go home I'm going to jerk him off "whack-a-mole" style.

While fucking doggy-style, right as the guy is about to cum the girl smacks him in the nuts through her legs and shouts "Whack-a-mole!"
Guy: I'm gonna cum, baby!

Girl: <smacking his nuts> Whack-a-mole!

Guy: AAAUUUGGGGHHHHH! FUCK! <groans and coughs>

Girl: I love you.

Get a whack-a-mole mug for your father Manafort.
A whack-a-mole consists of taking a huge mole (tobacco and weed in a bong bowl) and breathing the smoke into a balloon filled with whippit vapor (nitrous oxide) and inhaling/exhaling into the balloon until you're forced to breathe oxygen.
"Wow did you see that bro last night? Dude took too many whack-a-moles and yakked and then passed out....holy shit man."

A way to describe a chick who's had breast implants but one of the implants malfunctioned/deflated.
I saw Tammy and Gail together at the beach they were both wearing bikinis and each of them has an implant that deflated. So now when I see them it reminds me of whack-a-mole.
