What's on your mug?

Another name for the shiny top coat of nail polish. (It doesn't necessarily need to be the final coat applied.)

Go ahead and apply a glossy taco over your holo nail polish.

A joke made by Simply Nailogical viewers (who call themselves holosexuals). The nail youtuber used to say to apply a "glossy top coat" to the nails, which was misheard as "glossy taco" and was widely talked about in the comments of SimplyNailogical's (Cristines) videos. Cristine heard about this and now says "glossy taco" in her videos instead of "glossy top coat".

Christine: "Now we'll apply a glossy taco to our nails."
