1.
A sexual act in which the 'crabber' has a penis in each hand and is simultaneously tugging them off and popping them into his/her mouth. Crabbing can also include a third penis performing penetrative sex, usually an act associated with a female 'crabber' rather then male.
I love having two cocks at once, crabbing is my favourite hobby
