reindeer effect 

Something that cannot be totally explained.

Gentlemen, what we have here is a terrifying example of the reindeer effect!

Reindeer Effect 

The frustration after not being able to cum while fapping. (reference to the Christmas PornHub icon of a cute reindeer that stares at you.)

Dude, I tried to watch porn last night and got the reindeer effect.

Reindeer Effect 

The reindeer effect is as an instance where something that is gross, unattractive, unintelligent, savage, unappealing, or just completely awful in real life is redefined through cartoons and cultural representations as cute, cuddly, cunning, kind, attractive, or appealing. For example, reindeer and most animals or anything else that is personified through cartoons or songs.

I went to Africa and was nearly killed by an angry Hippopotamus that charged out of the river and attacked our Safari truck unprovoked! I didn't they were so vicious, probably because of how friendly they look on those Hungry Hungry Hippos commercials. I blame our lack of caution around hippos on the reindeer effect that that game has created.
