Bum-Gas means fart or a lady that has to much booty.
1. Mann that lady really has a Bum-Gas, Don't you think ?
2. Eww go to the washroom to let your Bum-Gas know one
wants to hear it or smell it.
It means looking at someones body from head to toe mostly not looking at their face
Why does that guy keep body checking me ?
I feel so uncomfortable.
Do I have 5 heads or something ?
