An individual that allows family and friends to treat them like shit. The individual gets tired of having to tolerate the bullshit treatment and will cry to people that don't treat them like shit and these people that never shit on that individual will be there for support. But then the individual wants to tolerate being shit on again by their family or friends and then the people giving the individual their support end up having to deal with that individuals shit.
The shitlover is a lost cause and always ends up going back for more so don't even get involved or you will be a shitlover too.
Man, that guy is such a shit lover.
