People who tweet someone else'e tweet as their own instead of re-tweeting them.
Eg:
Original finder of a funny article is ABC, while XYZ follows ABC.

ABC: This is funny. lol someFunnyUrl

XYZ who follows ABC tweets receives this tweet and tweets it as his/her own instead of doing RT @ABC: This is funny. lol someFunnyUrl

Thus, XYZ is a twitter leech, aka a tweech.

a Fake Social Media legislation that explains that one can tweet whatever he/she wants with no boundaries and openly doesn't care if you read it and get offended, all in 140-characters or less.
"Did you see Matt's tweet about jumping on the Winnipeg Jets bandwagon?"

"He's just using his Freedom of Tweech. That's the whole point of Twitter."
