Bert

Bert or burt
when you can see right down a girls cleavage
when a girls cleavage is clearly on display

This group of guys see a girl where she has a low top and they could see a quite clearly her boob
Once one see's her boobs, they will say bert/burt in a loud voice. Not shouting it out just saying it rather clear and letting other people who know of the meaning of the word that there is a girl with her tits showing
