I don’t know which I find funnier “fuck shit up” or “faire smashy smashy”

TO DO SMASHY SMASH

French: faire smashy smash 

English: to fuck shit up

Dont poor in the area of oolala omg

When I see stuff like this, I have to say something.

“Faire smashy-smash” doesn’t mean anything in French.
Or at least in French Canadian, since that picture was taken in the Montreal Metro (it’s street art btw). Actually, a Quebecer (or me) would probably just say “fuck shit up” mixed with some other french words or say “Il est interdit de faire de la marde”.
