Estus Flask 

An undead favorite. A gankers best friend. Probably tastes like Sunny-D.

"I was darkwraithing in anor londo, and some little shit ran away and drank about 15 estus flasks!"

Hydro flask 

The basic bitch of water bottles. Typically used by the quirky/annoying girls who say things like, spill the Tea. They'll often protect it with their life despite the fact that it is usually protected by a warranty and they cover the entire water bottle in annoying stickers.

VSCO Girls love their Hydro flask.

Hydro Flask 

A stainless steel bottle that keeps your water cool in a hot summer day with no air conditioning and only the noise of the tv as you lay on the floor complaining of the heat...

"SHUT THE FUCK UP"

Thermo Flask 

A weapon that is used by vsco girl wannabes who post TikToks every day and can only afford a Thermo Flask. They get so aggravated when they realize there's a dent on the water bottle, even though there was probably already a dent on it when they got their Thermo Flask at Five Below. Sometimes, they even pretend their Thermo Flask is a Hydro Flask, which is honestly no better.

Vsco Wannabe: "Check out my new Hydro Flask," *Hides the Thermo Flask label*
Vsco Girl: "Isn't that a Thermo Flask?"
Vsco Wannabe: "Shutthefuckup it's Hydro Flask!" *Whacks the girl in the face with her Thermo Flask*
