In the USA it's when you bust your nut in your hand and then slap the chick you just got done smashing. Preferably in the face but on the ass is acceptable.
Most commonly used in the UK and most of europe, a batter bomb is slang for a cum shot, or ejaculation load. It is only a true batter bomb if u catch the female in the face unexpectadly (sp)
DUDE,BRO i was fuckin this chick, i was about to cum, i pulled out and caught her in the face with a massive batter bomb! OWNED
(v.) The curmudgeon’s online equivalent to glitter bombing. The act of attacking someone on a blog or website comments page without warning or provocation just because you’re a bitter old bastard that has absolutely nothing constructive to add to the discussion and you enjoy being a complete dick.
We were having this really engaging onlinedebate the other day until that douche bag “4skin” showed up and begin bitter bombing everyone. Yeah, that pretty much killed it.
A Batterbomb refers to ejaculation. "Batter" is a shortened form of "baby batter" which is slang for malesperm. The "bomb" refers to its impact on a person's, preferably a woman's, face.
