When things get weird during intercourse and your partner puts two fingers inside your butthole only to pull them out and lick the "chocolate" off.
"She wanted to get kinky so I twixed her."
"How was it?"
"Grand. Just wish she didn't have Indian the night before."
"How was it?"

Twix is a slang quantitative word meaning £200. Coming from the fact that biscuit is monetry slang for £100, twix can be used to double up this value.
Tricky: Why is Mitch called Twix?
James: It's 'cos he said he'd suck off a man for £200.
Tricky: Oh right, like a biscuit, only theres two of them...
James: Bingo.
