bottomizer 

1. In gay relationships, a top who sees bottoms only as sexual objects. (Similiar to a womanizer in straight relationships)

2. A top who has promiscuous sexual relations with multiple bottoms, while paying no regard to the bottoms' feelings.

3. A top who has no respect and doesn't understand how bad it hurts when you just jam it in without lubing it up right.

I hate how Sergio comes home from work, then grabs a beer out of the fridge and doesn't even say hello. Then he just bends me over and rams his dick up my ass. He thinks that just because he has a bigger dick than me that he can treat me however he wants. He is such a bottomizer. On second thought, I wouldn't have it any other way.

Bottomless-kini

You've seen the monokini. Well, this is essentially the same idea, but the top is covered, and the bottom part is exposed.

Jodie wore a bottomless-kini.

Backyard Bottomslash

The very best kind of buttsecks: out in the open, scarin' all the neighbors.

(This actually references a character's NAME in the Japanese manga-based novel Death Note: Another Note. Although there wasn't much buzz about the name in Japan, the manga nerds of the US were laughing their...well, asses off.)

A. Signs you've been backyard bottomslashing:

1) You and your lover always have unexplainable all-over tans.

2) Your neighbors keep threatening to have you taken away for public indecency.

3) So do all those bastards at the pool.

4) So does your little sister.

5) You can't read the Death Note novel without getting turned on.

6) You know exactly how hard it is to try to get a grass stain off of your knees, chest, AND back...all in the same day.

7) And of course, it always helps if you're gay.

B. Nerd One: "Dude, I tried to read Another Note but I couldn't stop laughing at the buttsexx0r name!"

Nerd Two: "I know. I started an online fanbase for it, Backyard Bottomslashers Anonymous."

Bottoming-out 

Bottoming-out.
Known to happen to those of us with low-riding vehicles when we underestimate a speed bump or curb and --*eeeeesh!*-- end up momentarily having the speed bump or cub bump up kinda hard against the tender underbelly of our vehicle.

This term has another, newer, meaning though and of course it's a sex one.

"Bottoming-out" in bed is also when a woman is straddling her male partner and, only when her partner has a long-ish member, she tries to go deep and rest herself on top of his hips but *-eeeeesh!-* it's too long and the tender underbelly (her cervix or just the dead end of her birth canal, so-to-speak) is bumped kinda hard up against by the aforementioned member.

Women make the same exact face when either happens.

Bottoming-out.

I'm a little bit sore this morning after bottoming-out a few times last night with Ryan, dude. Eeesh!
