Someone who leaves a 1-star online review, just to troll a company.

shershers

Pejorative for super rich Chinese people. Named after the often used Chinese phrase for "thank you" (xiè xie) which sounds something like "sher sher".

"Look at those shershers with their gold Lamborghinis and Gucci bags."
