This is a slang variation on "forget". If you forget to do something because you were drunk, stoned, punch-drunk, you just had a lobotomy, or you made a typo - then you foprgot.
A phrase used in response to someone starting a new thread/conversation/tweet/etc... about a topic/website/video/etc... that was discussed ad nauseum by the rest of the civilized world a number of months/years ago.
The phrase is derived from the Back to the Future trilogy of movies which involved a DeLorean that could travel through time. The plot of the first movie in the trilogy revolves around the main character becoming trapped in the past when he can't refuel the DeLorean.
"You cannot say POP and forget the smoke" is a line that POP SMOKE (legend and listen to DIOR if you haven't heard of him) it was said in GOTTI by POP SMOKE and Travis scott.

They’re pills that create a sort of temporary forgettingness. So if somebody finds out how you do a trick, you just give ’em one of these, and they forget the whole thing. It’s a mainstay of the magician’s toolkit, like how clowns always have a rag soaked in ether.
A gut feeling you get when you're about to leave to go somewhere. You know you're forgetting something essential to your trip/destination but can't immediately place your finger on it.
The feeling is strange and based mostly on intuition, similar to deja vu. If you get this feeling, you may be tempted to dismiss it as a delusion, but after a short period of time something will trigger your memory and you will remember what it is you forgot. To avoid any inconveniences, the best thing to do when you get this feeling is to run through a mental or physical checklist on what you have packed and what you haven't.
This notion made an appearance in the 1990 family movie, Home Alone, when the main character, Kevin, is forgotten at home by his parents on their Christmas vacation to France.
Joe: "You ready for this trip to Amsterdam?"
Brett: "Hell yes, the only problem is that I know I'm forgetting something, but I can't think of what it is."
Joe: "Oh, don't worry about it... you probably just forgot to feed the dog."

Brett: "Shit! I forgot my passport!"
