semisocialize

To attend a large gathering of people where mingling with strangers is encouraged (e.g., a party or bar) but converse only with the small handful of people one arrived with.

"Those parties are bullshit for meeting people. Everyone just shows up and semisocializes in their own little cliques."

"The guy throwing that party might be douchey, but let's go anyway. We can drink his booze and semisocialize."

semiramis

1. One of the sexiest and most gorgeous girls you'll ever meet. The one you always want and the one that always spits in your face, when you try to fucking nail her. A goddess of sex that always gives the time of life to the few chosen ones.

2. Goddess of war

She is a fucking semiramis, she deprived me of my right of reproduction, when I tried to bury my boner in her backyard.

semibrity

- An actor or TV personality you seem to stumble upon all the time, but always forget or never bother to learn their name.

- A celebrity who (in your opinion) doesn't deserve to be that famous. (used as a minor insult.)

- Dude, isn't that the guy from Just Shoot Me?
- Who, dude?
- You know that tall bald guy in Just Shoot Me, he's a total semibrity?
- Shit, dude he ain't no semibrity that's Brian Posehn. He's totally famous in my book.
