When your bed is completely enclosed/surrounded by a bed sheet providing ample opportunity for "private time."
Options for building your wack shack:
1. If you have a bunk bed, the easiest way to create a wack shack is by sleeping on the bottombunk and draping the sheet over by putting one half under the top bed's mattress allowing for the other half of the sheet to hang down to the floor.
2. If you are not so lucky as to have a bunk bed, tacks and the ceiling are your best bet.
Benefits:
1. Noise reduction
2. Light reduction
3. Alone time
4. Girlfriend time
Joe just went into his wack shack...you know what the f*** is up.
A game where you and your buddies go into a room with a blanket for each of you. The next step is to turn the light off and all of you have to strip naked. Then, all of you start wanking off, but someone has to be sneaky and turn the light on. If you notice them, don’t confront him, pull the blanket over you. If someone sees your peen, you’re out. Last one wanking wins.
I went to the Whacky Shack with 9 friends.
I lubed my dick with my own shit in the Whacky Shack.
