Schlob

To give an aggressive and extra wet blow job.

"Gotta give a dick a good schlob."

"Stop schlobbing on my cock! Leave me alone!"

Cobbing

To nibble up and down the length of a shaft with one's front teeth. Like one would a cob of corn.

"They started cobbing my wiener! I was confused but then I got kinda into it."

"She cobbed my dick, dude. I don't think I'll ever recover."
