I didn't even notice that she had fucked most of the guys at work. She is very slutle.

phone: why don’t you go to sleep tommy it’s 2 in the morning?
tommy:why don’t you die you dumbazz

In a bar, a girl is sitting on a chair, a guy looks over at her and she pulls up her skirt.

Someone would say...

"that girl just pulled up her skirt so slutily."

or... if the action is clearly not subtle and and you want to be sarcastic then you might say....
"slutle!"
