Gallon Girl 

Female who becomes very appealing after consuming large quantities of alcohol i.e. 8 Pints/1 Gallon

Ooh! That's rough. A right gallon Girl. But after another 7 pints I'd have a stab at it.

Girl Gallop 

When a guy runs like a girl. This can be achieved by holding the elbows to the side and turning the palms up, swinging the arms below the elbows from side to side while running.

Dude! I thought Frank was one of us. Did you see him Girl Gallop over to his car? I'm definitely having second thoughts about whether he's straight or gay.
