and tilt your head to the side  

Smirk a little

Look him in the eye, look at his junk, and giggle.

Don’t giggle. Men like giggling.

A lot of women resort to giggling while attempting to insult a man out of instinct.

Don’t.

If a man is trying to creep you out and you want to hurt him, fuck off with the giggle. No need to soften the blow. No need to make it cute. If you want to laugh, laugh. Laugh a big, rude, viking’s laugh.

HAR HAR HAR HAR CREEPY FUCKING MAN
