look up any word, like the eiffel tower:
A man, typically between the age of 20-30, who enjoys and participates in chomping (the act of filling ones mouth full of pubic bush and repeatedly biting but, but not to remove or bite off hair) grandmothers.
Person #1- My friend Aaron is going to that ederly home an awful lot, do you think he's a granny chomper?

Person #2- If you mean he's chomping on granny pubes, then yes. You can see some white hair between his teeth.
