"Barmp" is a a Newfoundland term which is synonymous with "(to) honk your horn" and any other such variations of the word. Often times, however, the word is associated with being angry, so you may only "barmp your horn," if you were experiencing a bout of road rage.
"Buddy just barmped his horn at you!"

"Why do you keep barmping your horn?"
