Bah can be defined as Irish slang used to describe a friend who is being silly, cute or a wreck-head. You shouldnât only use the word bah for those you like. Bah is a derivative of the word bai, which is cork slang for boy.
You look great today, bah (cutie).
Cmon bah, we are going to be late (wreck-head).
I canât believe you forgot your vape bah.
