look up any word, like yeet:

BMSHOMP&J is an abbreviation much like "lol", "wtf", or "omg". It stands for "black man style hand over mouth pointing & jumping" because sometimes when african american males get excited about something, they cover their mouth with their hand, point at whatever they're excited about and jump up and down, usually yelling "ohhhhhh!"
