A quote from the movie Heathers and part of the actual song Big Fun from the musical Heathers. It has nothing to do with TikTok. If you think it's from TikTok or "that one TikTok song" consider yourself educated. Heather Chandler often says it to Heather Duke, and the line is revisited when Veronica yells "SHUT UP HEATHER" at Chandler's spirit. Please refrain from saying "dang dang diggity dang" is from TikTok, it's from Heathers.
Person 1: Shut up Heather!
Person 2: Oh my god, you know Heathers?

Person 1: What do you mean? This is from TikTok.

Person 2: What the fuck? No! It's not from that musical.ly rip-off, it's from an amazing musical!
