semi-formal

Wearing slacks and a button down shirt. No need for a jacket or tie.

I'm glad this party is a semi-formal party, I can't afford a jacket or a tie!

semmen

a different take on the word "semen", used sometimes as an escape for guys that are straight (questionably) but love using the word often in casual conversation because of its fun sound and comical implication.
especially useful for a guy whose friends are extreme homophobes.

-example 1-
zach: hey man, i was drinking some semen last night.
donald: oh dude, that's so gay.
zach: (goes over by the kitchen and pulls 'rewind' lever)
donald: hey dude, what's up?
zach: hey man, i was drinking some semmen last night.
donald: hmm, thats slightly unfamiliar, but i'm ok with it.

-example 2-
gabe: so today i went to blockbuster, licked some semmen off of a muscular man's pectorals, watched grey's anatomy instead of scrubs, and played some guitar.
meeka: whoa wait a minute! what was like the 2nd or 3rd thing you said??
gabe: licked semmen off a dude's chest?
meeka: no! the next one!
gabe: oooh, i watched grey's.
meeka: man you're such a fagle who likes guys and is gay; scrubs is way better than grey's anatomy... it has drama and comedy! and plus, people who just say "grey's" are even more gay.

“Semibisexual”

Apparently “a person who is bisexual but would never date one sex out of the two” no that’s just gay or straight, semibisexual doesn’t exist

“Oh Sarah is dating Lara”
“What’s her sexuality?”
“Semibisexual”
“Dude that doesn’t exist, she’s gay”

Dusty Semen

When you stuff some cocaine up your dick hole before receiving a blowjob, so when you ejaculate, your semen will mix with the cocaine and make your partner high as you orgasm.

Bryan fed me some dusty semen this morning, but since I had a severe seizure afterwards, I don't get to remember that lovely experience.

semi-sex

coitus which is stopped in the middle before ejaculation takes place; coitus which is not accompanied by ejaculation at the end. The male partner deliberately or otherwise withdraws his penis from his partner's vagina while still engaged in the sex. This act will deprive both the partners of enjoyment of orgasm.

Semi-sex is an incomplete sex.

semen exchange

A homosexual sex act in which two male partners put the tips of their penises up against one another, and ejaculate into each others' urethras. Not to be confused with cum swapping.
The verb form of this term is "to exchange semen."

After they were exhausted from pleasuring each other but still had not yet ejaculated, Danny and Jared performed a semen exchange with each other.
"I just love how you fuck me, Danny! Now let's exchange semen."
