flash cunt

A man, usually beyond his years, acting youthfully, usually found on a dance floor dancing out of rhythm, with an open shirt showing gold necklaces, bell bottom trouser or other ugly or unfashionable clothing, who entices young woman to dance with him, and who fails to do so repetitively but continues dancing night after night as if he was attractive, powerful and rich - which he is none of by appearance, reputation, and fact.

Look at Morris, that old flash cunt, dancing by himself at closing time, alone again in the corner.

Black Flash!

The name of an attack from animanga series 'Jujutsu Kaisen.' A Black Flash is a distortion in space that occurs when a sorcerers cursed energy is applied within 0.000001 seconds of a physical hit. When a sorcerer is able to do this, their cursed energy flashes black, and the force and strength of their strike is equal to a normal hit amplified to the power of 2.5.

Gojo Satoru: "Ya know. That "Red" just now... Still hasn't exploded.
Ryomen Sukuna: "Gah! From behind me..?!"
Gojo Satoru: "BLACK FLASH!"
