bum

of very poor quality; flimsy

the fleshy part of the human body that you sit on

he deserves a good kick in the butt

are you going to sit on your fanny and do nothing?

person who does no work

a lazy bum

a person who is deemed to be despicable or contemptible

only a rotter would do that

kill the rat

a disreputable vagrant

a homeless tramp

he tried to help the really down-and-out bums

ask for and get free; be a parasite

be lazy or idle

Her son is just bumming around all day
