look up any word, like ratchet:
Slob on my nob is a cooler way of saying suck on my dick.
slob meaning sick and nob meaning dick.

originally first heard from the band 36 mafia in a song called-slob on my nob.
Yo frank, slob on my nob!

Suck a dick, or perform fellatio to be exact. Slob being a truncated pronounciation of "slobber" an the nob being the dick.
From the Mafia 666 lyrics "Slob on my nob, like corn on the cob."
