What is a "subtweet"?

[__Suspended]

I've run into this term several times on twitter, and have no idea of what it is, or means.

It's the shortening of "subliminal tweet" which is directly referring to a particular person without mentioning their name or directly mentioning them and it basically indicates that the tweet in which the hashtag is used is a subliminal tweet.

Basically, it's talking about someone behind their back but sort of in their face on Twitter!
