SMROOKIES Girls are girls trainees from SM's predebut team. They are incredibly talented, pretty and funny and no one knows why SM still haven't debuted them or acts like if they never existed. You can sometimes see their fans (SRGnators) on twitter, complaining about how much they miss them and spamming their videos to anyone who dares saying bad things about them.
SRGnator: Oh My God, SMROOKIES Girls just got new content! Finally after 1215615621 years of drought!
Someone: Who???
SRGnator: SMROOKIES Girls, you know, this awesome predebut group who deserve to debut asap ! You should stan them, you won't regret it
Someone: Oh I'm listening to one of their 'Shining Star' OST and they sound so good! I'm stanning now!
