When a male partner licks butter (
peanut, regular, almond, truffle, etc.) out of a female counterpart's ear, while she smears butter (
peanut, regular, almond, truffle, etc.) all over his
penis, then proceeds to give him a foot job (a hand job, but with feet) with that butter.
"Oh my god, Becky gave me the BEST butterfooter of my entire life last
night, I was completely amazed by 'what
dat foot do.'"
"Do you mind if I hit up Becky? Heard her butterfooter
game was a 10."
