When you fuck a lady up the vagina for a bit whilst fingering her arsehole so that you can later secretly slip your dick out and shove your massive erection right up her arse.
I just doublebanged Elaine and she noticed and screamed for me to stop.
A female that obviously thinks she is hot, but in reality has both a butterface and a butterbody. Used alone or as a compound word, ie: doublebutter babe, doublebutter chick, etc.
Did you see that chick? She thinks she is hot, but she is a doublebutter babe.
