Someone who is a slag; a getaround or who sleeps with anyone and everyone.

Gets their pants down to whoever comes along.
If they are a slag, they have slagitude-they have the attitude of a slag/slut
"My God did you hear about Katie?"
"What about her?"
"She slept with Riley! Jenkins!"
"Nooooo way! Man she's got slagitude."

"Kelly slept with Tom last night!"
"She'll sleep with anyone!"
"I know, she has such slagitude!"
