When having sex with a lady friend you insert you finger into her bum hole and wipe it under her nose (see dirty sanchez) Later on - During the love making - While french kissing your lady friend you wonder - "What is that smell ?"
I gave her a "Dirty Billy" last night and I can still smell it.

When you cum on the upper lip of your partner, extract pubic hair from yourself and apply it to them.
