Momma Shmack 

When a 700 + pound, African American man breaks down your front door and proceeds to punch your mother in the face so hard that she crashes thru the nearest wall.

" Man !! Did you see Big Brian fuck that bitch up?"
" Hell yes !! That was a severe Momma Shmack !! I hope she makes it out of her coma."

shaolin shackles 

Unintentionally getting your pubic hair caught, snagged or stuck in a zipper while zipping up your pants or shorts.

The hippy chick that never shaves or grooms herself has the shaolin shackles and now needs a pair of scissors to free her pubic hair from the shorts she is wearing.
