BIHA or Break In Half Attack is when you have to shit so bad that your side starts to hurt and you feel like you are going to break in half
After holding my shit for 2 hours in that meeting had a BIHA on the way to the men's room.
Bitch Induced HeadAche. A headache brought on by excessive bitching or bitchiness.
Can you stop whining for five seconds? You're giving me a BIHA.
