A slimefuck is a person who is fucking slimy, and also retarded. the fact that they are slimy could refer to their lack of personal quality, hygiene, appearance, personal taste and lack of class, along with the fact they are a total dipshit and everyone hates them. generally all slimefucks are so shitty, that even other slimefucks dont like them, but this is not always the case. sometimes, slimefucks can roughly form together to form any number of slimy organizations, wether it be a law firm, real estate agency, used car lot, or political group.
"I spoke with a salesman today and he tried to sell me the worst tools I've ever used, that slimefuck. all of the tools broke, so I kicked his slimy ass"
"there was a slimefuck on the bus today that was eating a can of beans, and spilled em everywhere. his feet stunk, and then he puked on himself. got kicked off right after but the slime he left ruined the bus permanently"
