snabble

(transitive, Scotland) To snatch with the jaws; snap at something greedily.

(slang) To fellate.

To bite, nip, or pinch (someone or something).

One who gobbles.

Crude British slang for performing fellatio, derived from 'gobble' — to eat greedily or noisily — applied as a vulgar metaphor for oral sex on a penis. The term is blunt and explicit, more likely to appear in adult comedy, explicit fiction, or frank casual conversation than anywhere polite. 'Gobble' has been used as slang for oral sex in British English since at least the mid-twentieth century.
