I assumed you meant crouching (I remember a black and white picture of students at an American university squatting in a circle, with the explanation that it was a form of social equality because it put everyone on the same level, but I can't find anything about it on the internet), but occupying vacant buildings makes more sense https://en.m.wikipedia.org/wiki/Squatting_in_the_Netherlands
In germany used for" nazis raus"(out with nazis - idk) a common antifa-chant at protests aganst fascist gatherings (it is the letter N(azis) with an attached arrow pointing outside the circle (raus))
