A person who is mooched off of or sponged off of by ungrateful people who never return a favor and only think of their own greedy desires.
My mom is always a spongee...she lets people
mooch borrow money from her and never gets paid back. My niece is a sponge too...she let her sister
freeloader live there rent-free and never paid a dime to help with bills. They both need to kick those human
sponges to the curb!
