The definition of sluz is a combination of someone who is a sleeze and a slut. (someone who does not possess morals and does not practice personal hygiene)
A female who "sluts around" or acts like a total bitch to her apparent "friends," mostly male. She can be misleading at times and often tends to cling from guy to guy. Also, her mental state is not excellent, with her usually being "fried" or "cooked." She also has quick personality changes, which can usually happen from anywhere between 3-10 days.
"Bro shes such a sluz-dog" "I know right, the way she treated Mike, who does that" "Yeh she must be fried"
A chick (or guy) who you like to occassionally like use as a booty call and they will also do anything you like sexually for not only you but who ever you tell her to do so too, including mates, strangers etc.
" I got that sluz puppet to fuck me and three of my mates last and the guy from down the road last night"
