In others words like whats up cuz.
Or whats poppin with you and that girl

What's poppin Jimbo, is a meme that originated from Jimmy newtron the kids TV show, when Jimmy newtron's dad asks him like ''how's you're day?'' But instead says''What's poppin Jimbo?''. This meme is usually used when, you call to one of you're friends, then they say, ''What's poppin Jimbo?''

The first thing you should ever say to anyone ever in the history of the entire world I guess (also use 🅱️ At the end of every sentence after the statement what’s poppin 🅱️ Has been said)

Used to replace any word with a beginning letter of b. Bro, Babe, bae, etc.

This is a greeting meant to say what's up, what's crackin', or another such colloquial greeting. The reason it is popular is because Poppin' Fresh is the Pillsbury Doughboy's former name (the name was changed to update little Freshy's character and bring him into modern times). The phrase is not questioning what Poppin' Fresh is, rather it is using poppin' in it's slang meaning, and it is using fresh as a noun, not an adjective. Fresh refers to the person being addressed by the question.

Commonly used as a greeting/text. Can be extremely cringey at times, however if it used ironically, it's ok. 'B' is short for, 'Babe', 'Bae', 'BB' and so on.

Another way of saying "what's up"
