- propelled flow of cum in replace of snot as an sneeze
Hey babe don't rub your cock down my face tonight. I don't want cum in my nostrils. I have a big meeting tomorrow. Wouldn't want any cumrockets happening.

-- just imagine going to an important meeting and sneezing while cum propels and splats all over your bosses face

The fallout after giving a β€œmayonnaise booger”. Similar to a snot rocket, but consists of very dense semen.
That asshole thought he was funny by giving me a mayonnaise booger, so I blew a cum rocket back in his face.

It is when a guy ejaculates into the females/males nose and she/he blows it out like a "snot rocket". Sometimes she/he may let the spurm become crusty in her nose and pick them out therefore making them spurm boogers.
So Jenny didnt want to swallow it so I ejaculated into her nostrils and she blew a nasty cum rocket.
