knob on your cob

The act of sucking dick as if you're nibbling on a large, buttery, corn on the cob.

Slob on my knob 

1: blowjob

2:An AWSOME song by three 6 mafia

1: DUUUUUUUUDE she slobed on my knob

2: Slob on my knob
Like corn on the cob
Check in with me, and do your job
Lay on the bed, and give me head
Don't have to ask, don't have to beg
Juicy is my name
Sex is my game
Let's call the boys, let's run a train
Squeeze on my nuts
Lick on my butt
The natural curly hair, please don't touch
First find a mate
Second find a place

Third find a bag to hide the whole face
