Top definition
a person who always shows up to party/do drugs but never reciprocates drugs.
Referenced from finding nemo, but instead of the seagull saying, "Mine!" They say "Line!"
Person one: Dude, hurry up and do your line! Brian just got here!
Person two: Aw shit. Who invited the damn trap seagull?!
