Though there is no scientific evidence on the subject, in researching this article, we’re fairly sure that roughly 1 in 4 men and women aredatingan honest-to-goodness douche (yes, women can be douchebags, too). Read on for true encounters so shocking, you might feel compelled to take a shower…in bleach.

1. Choosing to run, hide, deny and ignore instead of communicate respectfully and effectively is cowardly at best and often douchey.
2. Shirtless photo-in-the-mirror profile pics? Douche. Duck lips? Double douche. Oompa-loompa orange tan with frosted lips, fake nails and tramp stamp? Run.
3. You sleep together, he drops you off the same night and says, “Well, thanks for coming out.”
4. Any guy or girl who makes you feel insecure on purpose is a douche.
5. If he knows about “The Game” and thinks it’s “cool,” bye.How old are we?
6. Sorry, ladies: If he only calls you for last-minute dates, you’re plan B or C, and it’s just aboutsex. As they (as in douches) say, “a side chick will never become a main chick.”
7. You’re sleeping together but can’t be Facebook friends or see his Instagram. Red flag!
8. He acts into you, you sleep with him and then he says it’s cool if you see other guys but wants to continue sleeping with you. Ladies, this is not someone you want to spend time with. What dude wants to share that? Oh, we know: a douche.
9. Any man who pushes you to be exclusive, swears it’s destiny, promises you the sun, moon and stars, talks about your future on date three is either a douche or a stalker.

15. He says, “I’m glad we’re on the same page about wanting kids–and getting rid of the baby weight quickly.”
16. He tells you to dye your hair from blonde to brown to get a boyfriend,because attractive blondes are seen as “F*ck Toys.”
17. He or she is dating men/women who are two decades younger/older and are hotter/richer than them. It must be because they havesomuch in common.
18. He gives you IOU’s–actual IOU’s on torn cardboard— instead of gifts on special days.
