Butterin Toast! 

v. The act of jizzing on someones freshly toasted toast and smearing the warm creamyness over the toast and watching them eat it.

Rachel gazed over at the seemingly innocent toast on the counter top. Little did she know of the sinister Butterin Toast! ritual that took place in that kitchen.

When you're having sex with a girl and you pull out to ejacualte on her crotch and start spreading it around like butter on toast.

My girlfriend wouldn't let me cum in her so I ended up buttering the toast
