seapickle

A turd that floats, usually left by careless swimmers.

There were no restrooms at the beach, so I left a seapickle in the surf.

Semicolon

A type of punctuation most commonly used to separate related independent clauses. They're underused by the majority of the population; however, they are quite helpful and can be very versatile when implemented by a skilled writer.

I have written and submitted my defintion; I expect to be notified upon its addition to the site shortly.

Bitches don't know about my semicolons; but man, those bitches love 'em when they see 'em.

semi

the state of a penis which is not altogether flaccid nor erect. It will often occur at inopportune embarrasing times and will be brought on purposefully by a cunning sexy woman pretending she has no idea what she is doing.

"why are you still friends with some of your ex-boyfriends?"

"I like to keep them healthy and providing the regular semi keeps the circulatory system in check."

Semiconductor

Material that only conducts electricity when it feels like it.

I called my CPU a jerk, and now it's not working... damned moody semiconductors.

semi-boner

When ones penis is no longer erect, possibly either after blowing ones load, or just losing an erection. A semi-boner is often used for playfully slapping ones friends in the face while they sleep for a hilariously good time.

To try and piss my friend off, I got a semi-boner and helicoptered it around in his face.

Raging Semi

1. An apathetic boner.
2. It's hanging in there.
3. The point right before a full blown hard-on.

That chick gave me a raging semi.
