Homemade Sash

A term used in competitive Pokémon when a Pokémon survives an attack from full health at 1 HP, despite not carrying a Focus Sash item or having the ability Sturdy. Usually a Homemade Sash has a very notable impact on the battle, often making the difference between a win or a loss. This term was first used by Pokemon Showdown user Xeno Disconnected, when fellow user Escaval's last Pokémon, Mega Sableye, lived an Alolan Marowak's Flare Blitz at 1 HP, allowing it to take said Marowak out with Knock Off and winning the game.

While originally the term was only used when a Pokémon lived exactly at 1 HP, thanks to Pokémon Showdown's HP Percentage mod the term was also used for any attack living at 1% HP, which could usually also be 2 or 3 HP. Later the term also got used for any attack being survived at 1% HP, even if the defender wasn't at full HP, under the motto "Homemade Sash: Works anytime, anywhere!"
