Portuguese Flashbang

When you cum in a girl's eyes and face and smack her ears simultaneous, similar to a Russian Flashbang, then just run away (assumingly to play football)

Dude 1: She wanted me to stay, but I gave her a Portuguese Flashbang because I had a match with the boys!
Dude 2: True bro right here!

Poseidon Flash Flood

When you’re dropping a load in the toilet that’s too much to go down and the water level rises up so that your balls get dipped in the broth, but ends up flushing after all before the bowl overflows. Result of not performing courtesy flushes along the way

After sitting on the toilet for over half hour scrolling my morning social media feeds, I realized my legs fell asleep when I flushed and my balls were submerged in a Poseidon Flash Flood and I couldn’t get up in time to turn off the water. Luckily it was a flash flood and ended up going down the toilet

NA FLASH

When a league of legends player (possibly pro) from the North American region uses the in-game flash summoner spell in a terrible and possibly game losing way, we define it as a NA flash. The term is often used by people from the Europe West region to make fun of the NA region and players, but unfortunately they are equally as bad and have not won Worlds in millennia.

Twitch Chatter 1: NA FLASH HAHA
Twitch Chatter 2: Nah but EUW
