When it is so cold your vagina freezes shut.
"How cold is it?"
"Its so cold I have a burrgina"
A much more sophisticated way of saying vagina.
It should be pronounced as follows:
Burr- = Brrrrrr
-gina = j-eye_nuh
The emphasis should be placed on the j-eye.
Milton is such a burrgina!
Milton is such a loser, he can't pronounce burrgina!
