Uno reverse card 

A powerful weapon of mass destruction used by the Soviets during the battle of Pepe where the radical meme group JOE got asked who joe is witch led to the death of 69 civilians and 420 injuries. The Soviets used the weapon after their motherland was called gay. JOE quickly surrendered but the Soviets had to give up the use after the U.N's ban, due to the increased threat of sanctions and their economy starting to run dry.

Why did I waste my time, was this worth it?

The Uno reverse card killed thousands of blind crippled retarded orphans.

Uno reverse card 

The best comeback to figuratively and metaphoricaly any argument even if you are already winning. Its impact and feeling contributed in the argument can be summed up in many ways. It is The equivalent to no u, the literal godsend to a victorious argument, the diamond glaz main on plane, the awp in mid, the child predator to church, the yin to the fucking yang, the water bucket to a 50+ block drop, the gaming chair to youtube rewind, the 360 mlg no-scope to any call of duty, the ammo crate to an assault player, the woohoo to a slease sim, the opium to before now china, the smell of napalm in the morning, the thicc belt to your ass, the literal equivalent to fucking god

Your best friends mom
