You can get temporary tattoos now, or body paint that looks like a tatoo. People generally only notice piercings when they are stretched or when they contain jewelry.

You’re playing into the trope of the “overly emotional and erratic” woman here. The emphasis should not be that the woman who employs such tactics to get a break from male pursuit will come to regret it in time, but that the constant pursuit of women who are clearly not interested by many men causes the need for such extreme tactics just to be left alone in the first place.

Frankly, these are brilliant. Knowing how to make yourself unattractive to someone who’s creeping around, or a guy you dated but won’t let go, etc., is a great way to avoid potential stalker problems as well.
