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*
