Someone who survives off anothers income. Someone who believes that they are owed something for nothing. One who even if they have their own money, food, clothes, etc. will still use someone else's first. Even if that someone else is more poor.
I can't believe you are letting him stay here! All he does is eat our food, drink our beer, watch our t.v. and still has the nerve to ask us if we can loan him money! What a moocher!
Dude, quit moochin all my beer!
That moocher isn't getting a dime from me!
