When you put a stick of butter up a
pussy for lube. Typically the
pussy will warm the butter if you stick it up far enough and the butter will melt, lubing up the
pussy from the inside out and it sort of resembled a Piss-gasm liquid when it oozes out. At this point you would stick the dick inside after fucking you can finish with a blow job and your partner will experience a barrage of magnificent flavors that result from a cum-butter mix. see def. Cum-Butter.
Gf - Hey babe were out of lube you wanna use spit?
Bf - Nah lets just use some
butter
