ok so here are all the trends I can think of..
Rainbow G.a.y support trend: Started About December 2016-late January 2017
Red scribbles on faces of profile pics: Started About early February 2017-???

Comment below what the next trend should be or if I missed any...

 

There should be a trend where your just yourself and not a sheep.

 

quotes seem like a trend

 

When you accidentally start the red face trend just because you don't want people to see your face ;-;
