Phonetic spelling of a burst of maniacal laughter. Used mainly in casual-texting enviroments such as email and im; bwahaha indicates triumph, scorn, and evil scheming.
Alternate spelling: 'mawhahaha.'
Natalie will me no match for me at the party; I will triumph due to my sassy boots and my superior cup-size. Bwahaha!
a fight or some kind of argument between more than just two people. This specific kind of fight is usually just verbal because when it's physical, it becomes a bruhehe. So typically, bruhaha's are just between girls, but not always.
