My explanation for this is an inside joke between my friend and me (they also like tmbg)
If I were to make up an scenario to explain this it’d be: Linnell tells Flans one day about mewing and how it’s bs and it pisses him the f off. Flans takes advantage of this by repeating the same gesture in the video every time he wants him to shut up (it always works).
Anyhoo, have some other Here comes Sciences doodles :*]
And finally me & my friend’s sonas (I’m the green one)
