A true dry hump involves taking off all clothes except for one partner's pair of underwear, penetrating as far as the fabric barrier will allow, and doing a sort of hybrid grinding/thrusting motion until the man cums.
Dry humping is mostly commonly associated with teenagers, who either do it because they're scared of the potential consequences of sex or claim to be committed to keeping virginity. Many teenagers perform similar actions with more layers of clothing on, but this is actually considered grinding rather than true dry humping.
Dry humping also takes place among couples, usually when either 1) the mood strikes and there's no condom on hand or 2) the girl is on her period and doesn't want to make a mess. In the former case, the man keeps his underwear on; in the later, the woman does. It can be a pleasurable changeup.

1) "I'm so horny, Kristin." "I know, Michael, but remember our promise rings. We can dry hump but we can't have sex."
2) "I'm so horny, Kristin." "I know, Michael, but now that we're adults who no longer give a shit about our promise rings, you need to remember to bring a condom. We can always dry hump."
3) "I'm so horny, Kristin." "I know, Michael, but I'm on my period. It won't be as messy if we dry hump."

Dry ass is when u wipe to hard and your asshole gets all dry and that skin cracks and u start bleeding. There is no known cure for dry ass. It is the absolute worst.
“Dude I was just walking the other day and felt a sharp pain on my asshole. I then realized that I had been struck by dry ass for wiping too hard when I took that massive dookey earlier today.”

Someone who indirectly rats you out. A dry rat doesn't think they are ratting you out because they aren't directly ratting you out.
My girlfriend was complaining about her sore ribs so loudly that my neighbours heard her so now they think I am beating her up. She's such a dry rat.
