A holo taco is... well. Hm.
Lemme explain holo first.
Holo is short for holographic, which is something shiny that can come in any colour or form, that when light is reflected off it, it shines rainbow MAGIC SHIT!
Or for the idiots:
Holo: holographic glitter
Taco: a simply nailogical (Cristine with no ‘h’) abbreviation for top coat.

Or, holo taco could mean simply’s new nail polish line! It’s beautiful cristine I own one
Now let’s add a hOlO tAcO to seal it allll in!

SAR HOLO: also known as Semi automatically rifle with a holographic sight. Which is the worst thing people can use on a gun in rust.
Example one: COMS COMS COMS I NEED TO KILL THESE zergnuts with my sar holo
Example two: a retarded person who uses sar holo to oil rig you know who you are

Simply Nailogical is so obsessed with Holographic Stuff, She’s a Holo Sexual

In the Nail Polish Communities Holographic Nail Polish is loved for its colour-shifting properties, so much in fact that Simply Nailogical coined the term holosexual (someone who is sexually attracted to holographic things). Someone who regularly flaunts holo gear is often referred to as holoslut.

From this scene grew the expression "How Deep Is Your Holo?" Referring to the big question of: are you a holosexual or just holo-curious ?

The correct answer to this would be to reply with the second line from the Simply Nailogical - Adele Cover of Hello , aptly named "Holo" : "Like The Ocean" - this would mean that you are familiar with Simply Nailogical, and open about your holosexuality.
I see you have a lot of holographic nail polishes, how deep is your holo?
