You aren't getting old...it's fairly recent. It's related to Thomas Nassiff's review of Transit's latest release, Young New England. The review was negative and there were many subsequent posts agreeing that the album was subpar. The backlash resulted in a trending hashtag (#) on twitter --> GFYTN
Haha, you forgot to say what it stands for.
I assume it's "Go Fuck Yourself, Thomas Nassiff?" Did someone from Transit, or Transit fans start using that hashtag?
Apologies for being out of the loop (and my apologies to Thomas if that's not what it stands for).
