Saying 'Money Before Bitches' takes too much time. MBB is so much easier, no? As in: "MBB, bro."

mbb 

MBB means My blood boils. It is used at the start of a sentence that begins usually like, "MBB when". This is similar to FML that it mentions an anecdote but different in that MBB comes at the beginning while FML is said at the end.

MBB when I take a shower and then I have to poop immediately after it.
