Girls who reply to popular videos on Youtube just to get views.
They usually have their boobs hanging on the thumbnail to catch viewers then make a short video explaining stuff you already know. Also can be called the spam on youtube.
Random kid. "Oh I just watched nighahiga's newest video!"
*sees a reply video that has a girl with a huge rack as thumbnail*
" I wanna watch that"
30 seconds later...
"That was f**king dumb as f**k! I hate these reply girls!"
