Bad breath aside, the WORST kind of kisser in the ENTIRE WORLD is anyone who has both of their lips on top of yours. Luckily for me, I've only had this happen to me maybe a small few times in life, but II really feel sorry for someone when I see it happening to them.
I'm like, how do those kisses even happen...like, what is your goal when you kiss like that!?!
These type of kissers also seem to think you don't need air.
Also, kisses with too much moisture (I won't paint a picture beyond what your mind is thinking at this point). If you've experienced this, you know how awful it is.
