mouth slug

When one slithers their tongue on their partner's neck; creating the sensation of a slug sliding around on their neck.

Yo, last night, that chick was giving me the crazy mouth slug.

slug mouth

When someone is sucking dick and it’s not soft but it’s not hard either

Boy: yo that girl is a major slug mouth
