A catchphrase made popular by various High-School Bimbos and Darren Criss of StarKidPotter. Used in reference to something cool and fun; more than partly awesome. Can be heard many times within "A Very Potter Musical" (formerly known as "HP the Musical") both in song and speech form. It is now a phrase widely used within the Harry Potter fandom (thank you, Darren).
I'll cast some spells, with a flick of my wand
Defeat the dark arts, yeah bring it on!
And do it all with my best friend Ron,
'Cause together we're Totally Awesome
This year, you bet, I'm gonna get outta here
The reign of Malfoy is drawing near
I'll have the greatest wizard career,
And its gonna be Totally Awesome
StarKidPotter is Totally Awesome
