Lag Slag
A girl you phone when you're too tired or too wasted to bother with anything decent. She's usually not hot, but she's happy to take what she can get.
Lag Slag, I'm too wasted to find someone else. Just come over.
You're my last hope, Lag Slag. I don't even know why I call you.
I'm too lazy to find a real girl. Lag Slag, I need you now.
