the sound made when someone gags while giving a blowjob. (the 'C' is silent)
getting a blowjob, listening to her slurp and smack her lips, all of a sudden "chu...chub...chub...CHUBBUCK!" (the 'C' is silent) she gags a little! no prob. slow your roll playa and begin again.
the word chubbuck comes from the ancient greek, meaning 'to choke with dick'. lost for centuries, the word has a new found audience with todays hip youth.
example: "She really chubbucked last night. (on my dick)", or , "I sure hope your huge cock doesn't make me chubbuck. (because of the enormous size)(it's huge)"
When you hand craft a stone or rock dildo and super glue it to the tomato mascot outside of Fazoli's and paint it bright pink so that little kids stare at it in envy.
"Look Mom a chubrock. Can I sit on it and you take a picture?"
"No, Billy, maybe when your older"
