A sponge is a thirsty fuckboy who finds any opportunity he can get to ask for nudes. He says things like "Prove it ;)" multiple times a day. Usually less confident in person. Girls HATE it when a sponge trys to slide in her dms.
Wow Brian is such a sponge, this is his third time asking for nudes today.
