When a big shit is stuck to one of the sides of a 'bowl', and is slowly sliding down, giving the impression of a brown slug slowly slithering its way downwards.
"Yesterday I ate so much pizza, there was a slug in the toilet."
"HOLY FUCKING SHIT! Bad dog! How many times have I told you not to unleash your slug in the back yard!?!?"

slug can mean anything. it can mean i love you, i hate you, you look pretty. absolutley anything. it is mostly used for negative things, but can also be used positively. it is an adj.
"Wow you left my party early, you are such a slug."
"You are totally wearing my shirt slug."
"That party was so slug!"
