Mango!/Spirit Gun!

Origin
The word 'vengo' in Spanish means "I'm coming". Jonathan yells it whenever his mom calls for him. When Rowan was younger, he liked to think Jon was yelling "Mango!" After Rowan shared that with him, it became a meme. It devolved into a nerdy, beta male shriek.

Description
You do it by stuttering in a nerdy weakling's voice ("dyeh-dyeh") and then shouting "Mango!" in the same voice.

Uses
It's used after impersonating Jon's mom yelling "JONATHAN!!!".

i.e. Papi Guapo- "JONATHAN!!!"

Papi Chulo- "Dyeh-dyeh-Mango!"

Spirit Gun!
Spirit gun (or Rei Gun in Japanese) is a move used in the '90s anime Yu Yu Hakusho by protagonist Yusuke Urameshi. It involves holding your hand like a gun and shouting "Spirit Gun!", and an energy bullet flying out of his index finger. This meme is done by imitating that, but first stuttering in the beta male voice and then yelling "Spirit Gun!" in the same voice. (i.e. "Dyeh-dyeh-Spirit Gun!")

A variation of Spirit Gun! is the 'Inverse Spirit Gun!' which is starts the same: You start stuttering the beta male voice for a few seconds, but instead of yelling "Spirit Gun!" in a shrilly voice, you say it in the deepest, blackest, thuggish voice you can possibly do. (i.e. "Dyeh-dyeh-SPIRIT GUN")
