A slag is the top crust of the bread because everyone touches it but no one likes it just like a slag as in a man or woman slag.

A woman that fucks around behind her friends or lover's backs with numerous men, with no feeling what so ever for the people she is hurting. A trashy, deceiving, back stabbing, lying heart breaking, cunt. Doesn't care what she does or who she does it to, as long as people are talking about her, weather it be good or bad, she's happy. Wherever she goes, drama is sure to follow.
"You slept with my boyfriend, my best friend, and my brother !"
"haha, yeahh, I hope my boyfriend doesn't find out."
"You fucking slag."

a word used against women/girls by men/boys to insult.
it basically means someone who has slept around alot or has done other sexual things, people often use this in irrelivent situations, by saying it to someone who isnt a slag at all.
person one - i shagged him last night
person two - you slag!
