What does this >>> and this<<< mean on Twitter?

[Taylor]

I kinda just joined a couple days ago and was wondering what does it mean?

[Amber]

It means the same thing in math. So you just prefer something greater or less than something else. That's all.
PS: it's okay to leave something on the other side.

Bigger than/less than signs. So ok for example, if I think Seth rogan is hot/funny/fav actor/whatever, anything GOOD, I'd say Seth rogan >>>. The number of those things depends on how strongly you feel lol. If I hate school I can say something like 'waking up early in the morning <<<<<<<"

[thankfulpie566]

Sometimes it means greater than or less than (or better than or worse than). So like a Justin Bieber fan could say
Justin Bieber > Jonas Brothers
because they prefer Justin to the Jonas Brothers.

They can also mean arrows. Like
This face >>>> is so cool.
