Back. Up. Bitch.

It’s in the name. People with B.U.B’s are these high and mighty douchebags that seem to think they can get EVERY girl like it’s just some kind of pool of girls he picks from one a month. But they secretly don’t know if the girl they simp for will say yes, so they need a backup girl to send him booty pics or just another girl because deep down inside they are very insecure. There are two types of B.U.B, BUB singular and BUB plural. BUB singular is just a guy that can’t make up his mind because he is a bitch baby. Then there’s BUB plural...... this is the highest degree of man hoe. Not only does he want other girls as backups for the one he simps for, but he wants to use girls and say I love you be my back up bitch, then just says “oh forget about it”. There is always two BUB’s for some reason. One is like better than the girl he simps for in every which way but they don’t like her because she isn’t as HoT as the other one. Usually the main bitch steals everything from her and she is sick of it. Then there is the second BUB and she is the most knowledgeable because she dated him and he used her for nOoDes. She takes no shit and also hates the main bitch. But both BUB’s cut the shit and become friends so they can talk shit about the other ones. So inevitably he ends up alone because he breaks her heart. As my dad says, “It’s ok to be cool, just don’t freeze”.
He has Sooo many B.U.B!

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
