A form of self pleasure whilst thinking about some one you have obsessed over. i.e. masturbating while thinking of some one you have a big crush on.
'I would like to go to the concert but Sam is having a crosb'
'Dude I can hear you crosbing through the wall.'
'It is clear that we will probably not have sex tonight so excuse me while I go and have a Crosb.'
