To crush the memories of a person / event / thing completely, as if nothing had happened and they
don't exist, or just simply forgetting everything. Just like what the Communist Party of China did after the 1989 Tiananmen
Square protests. Tank
man
I had a really great word to put up on Urban
Dictionary but I Tiananmen squared it !
Friend: Hey, how's things between you and your girlfriend ?
Me: Oh, she's my ex-girlfriend now, we broke up
Friend: Oh, you must be feeling really bad right now
Me: Oh, no no no, I Tiananmen squared her. Who was my girlfriend ? Nothing happened.
Me: Hey, ready to take your
math exam tomorrow ?
Friend with extremely bad memory: There's a
math exam tomorrow ? What is
math ?
Me: Oh no ! It seems like you Tianamen squared everything ! Well, good luck for tomorrow's exam !
