Short for "Bag it, and shag it". When a girl (or guy) is too ugly to look at their face, you put a bag over their head, and then you can do them without guilt.
TIP : If you use a european designer bag, it makes her even better.
You may be as ugly as horses ass, but with that bag on your head, you can ride my pony anytime.
