Someone who can't make or keep their own friends for very long, and therefore rely on taking friends from the only people they know and making connections with them before taking out the person who introduced them in the first place.
When your cousin/sibling becomes a friend sponge and soaks up your friends like they've known each other for years when you only introduced them at that party last Saturday.

sponge dope aka sponge bob dope is chunk dope / fent dope with a distinct yellow color, typically after being dyed with food coloring. Since bricks of yellow fent dope are square in shape, some have suggested they resemble Spongebob. As such, dealers and users often refer to yellow fent dope as sponge dope, bob dope, or sponge bob dope.

Spongebob’s sponge theory is a theory which we absorb ideas like a sponge, and where some slip through the holes and others are squeezed out of us in every day life, like a sponge.
