Whack Attack

When one uncontrollably starts to infectiously giggle, seemingly about something simple. Even after brief stints of composure, the whack attack continues.

They got so high they had a 2 hour whack attack when the reporter accidentally said 'poop'...

meaty whack

This is a sound effect for some things like a comic relief, or if it’s a sound that comes from having sex. Often a joke to make your friends chuckle till they have a asthma attack.

Example 1:

John: *makes a meaty whack on his thigh*
John and Steven: *both chuckle*

Example 2:

Bruce :I’m gonna roll in this locker room with my big dick! *sets his dick on a table to prove his dominance, henceforth causing a meaty whack*
