a contraction of "that's word" and "it's word," hence s'word

Another rendition of "that's my word" meaning "I'm serious" or "that's the truth" or even "that's a fact". Essentially, you're trying to get across that you really mean what it is you've just said.

What someone says when they have done something for the purpose of maliciously disrupting another person(s) motive, intentions, life, job, etc, and the victim asks that someone why they did it.

Word means I agree with you.

Another way to add sex to innocent things without saying "that's what she said."

in (word ending in "er) her, i hardly know her, "Her" is the same person as "She" in that's what she said. It's a hypothetical girl that you have sex with.

When someone says a word ending in "er" you turn it into a sex joke.

So if a friend says, "Dude, I broke your windsheild wiper."
You say, "Wipe her? I hardly know her!"

a word that is used way to much to the point of annoyance, and to a point where everyone uses it just to sound like everybody else.

A depraved sport enjoyed by bohemian arty types. The participants strip off and stand facing each other. On the referee's word they "engage" their genitalia and commence a sickening battle of diseased phalluses. The depraved spectators roar their approval of every thrust and slap, quaffing champagne throughout the contest. The winner is determined after one hour of cockmanship by 3 judges who award points for artistry, scabbiness, and blood-drawing. The winner enjoys a golden shower from all present and gets to bugger the referee's spaniel. The sport was named after Briggsy, the world's greatest arty bender, who invented it whilst celebrating winning the Turner Prize for his sculpture of a gorilla fucking a shark to death.
