biscuit fucked

biscuits are undoubtably filling, but when used with the word "fucked" we are relating the state of being full with two sexual acts, creampies and swallowing

For Example:

waking up drunk from a party
"i don't know what the hell happened last night but i know i got biscuit fucked"

"that bitch straight up got biscuit fucked by ________, u know that hoe's pregnant"
