When you happen to destroy 4 people in row or at time.

It bears the same meaning as "Quad Kill" in gaming language.

Based on the word "rekt" (To beat/defeat someone utterly and absolutely).
A: Man, you kicked those four guy's asses really bad. That will show them not to mess with you!
B: Yeah, it was quite a rektangle.
