When someone thinks they have invented something that's been around for awhile or has already been discovered but tries to take first claim to inventing it.
hey man I just mixed sauce, meat, and noodles together and it's amazing. You should try it. I've never seen it before.

When you and a partner(s) have sexual intercourse and finish in every single room of a house, apartment, or other building.
Them: Have you heard of Columbusing? It's when you smash in every room of a house!
Blake: Oh yeah! Sophie and I Columbused in her house the other day! I don't think there is a single square foot of that building that we didn't bang on!

When a non-white racist posts a definition on Urban Dictionary and uses his ignorance of post-Moor-invasion Spain to act as though he's being clever by ripping white people for claiming old shit as their own.
Dave: "Hey, bro- check out this ignorant definition in the Urban Dictionary-- this dude thinks Columbus was white and he's pretending that only white people claim old shit like they invented it."
Jamal: "Hang on, I gotta finish this beat I made out of an old Lynyrd Skynyrd sample for this album I'm burning so Rihanna can put her name on it... Oh, damn! Yeah, even I have to admit he's Columbusing that shit."
