sock.clip (known on Instagram as Rounded Triangle) is the composer for Friday Night Funkin': VS. Whitty, and the real creator of Gabriel Updike and Whitmore. She worked with two other people (Nate Anim8 and KadeDev) to make the mod.
Whitty originally had Overhead when he was a replacement for Dadbattle (a song by Kawai Sprite, the main Friday Night Funkin' composer). The three worked together to make the full Whitty week, making two new songs (Lo-Fight and Ballistic) as well as putting in Overhead as the second song.

For a while, sock.clip has left the FNF community for:

1) The general toxicity of the community
2) Homskiy, fellow modder and creator of V.S. TABI Ex Boyfriend, being harassed after sock streamed on her Instagram profile.

However, after a surprise announcement of a remastering of VS. Whitty, sock.clip seems to have returned to the modding scene for the time being.
