The saying is "the sluttiest thing a man can do is (....)", followed by something mundane, but can also in one way or another be ultimately sexy. 

It's Twitter lingo, and after coming across some of the 'sluttiest things', we listed down the 11 things men can do based on research which categorizes as such. 

We hands down agree, check it out. 

1. Take pottery classes - oh if that isn't a sexy hobby

2. Order appetizers - he takes his time honey

3. Know his big 3 (horoscope - sun, moon and rising) - soul deep

4. Know how to cook - we mean???

5. Major in English - if there isn't something so inherently hot about good English

6. Work as a barista - yes, yes and yes

7. Be a 6'4 - no offence to shorter men, but tall men TT

8. Listen to Taylor Swift - so you wanna maybe get married?

9. Have tattoos - .....

10. Play instruments - play me like you play that guitar you talented gorgeous man

11. Is all round a clean person - goes without saying

Course, sexy is subjective, so grain of salt, BUT still sorta true ;)
