What is Tweech?
1.
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.
