It's truffle butter, but when a girl is on her period as well.

It can also be Red Velvet for short.
I was hoping to get a little truffle butter, but the chick was on her period, so it was red velvet butter instead.

Red Velvet Truffle Butter is when you pull you dick out of the asshole an continue fucking her pussy while she's on her period. The substance around her pussy is red velvet ruffle butter (cum mixed with period blood).
Baby, I didn't know you were on your period, now you got red velvet truffle butter happening.
