User blog comment:Gaybagel23/Just Dance: Sugoi Sosu! (すごい／凄い ソース)/@comment-26699584-20181114135502/@comment-26573805-20181114142750

Sugoi in this context means "awesome". It can also mean very, so sugoku kawaii means "very cute" or "sugoku nagai" means "very long". It can mean awful in terms of describing something that's contextually awful, however that's not usually what it means without that kind of context.

Nonetheless, Sugoi Sosu is not a phrase in Japanese like "awesome sauce" is in English, so I would avoid using it. Besides, it can be interpreted as "awesome sauce" or "awesome source", based on how the katakana is translated.
