These are the top five most commonly heard Vine phrases/memes that you would hear somewhere.
1
"YAAAAA!!"
As crazy as this sounds, this is still used all the time. No words are needed for this one...
2
21!
Whats 9+10? 19. Not 21. This was the most popular Vine for a while. From late 2014 to early 2015, this Vine was a big hit. You can still hear someone say this, but its a little rare now.
3
Watch me whip/nae nae.
This is very common. I'll be honest, I've done this MANY times... there isn't much to say about this.
4
DEEZ NUTZ!
You can't tell me that you've never heard somebody say this. Because everybody has. This is very common to hear.
5
WHAT ARE THOOOOOSE?!
The most common one around. This is my favorite one, and is the most commonly heard one of 2015. [IN MY OPINION!]
