Her holographic purse is everything!
The rainbows shifting under that sun roof is holosexually arousing me!
The pokemon card everyone wanted, and thought was so rare, but every kid on the block actually had one. A badass mother fucking fire breathing lizard.
Joe: holy fucking shit, I just got a holographic charizard in my pack!
Dave:dude, so did I! It's so rare, we must be the only ones in the state with them!
Joe: this card is worth so much money!
Holographic, also known as Holo, is a hologram. Do not mistake Iridescent for holo, it is NOT holographic. Iridescent shifts to only a few colors, unlike holo, holo has all the colors of the rainbow.
