Question to the russian players

Hey there kind russian CS:GO player!

I have a question. What does "rush" means for the russians? In my dictionary it means, to attack one of the bombside fast, to catch the defenders off guard, and get a fast advantage over the other team. However every time i play with russians they seem to have a different meaning for rush.

2 examples:
Map: Dust2 T side. We get a nice B spawn, so one of the russian guy says: rush B. So i go, as fast as i can, just behind this russian teammate. As soon as we reach Upper Tunel, he starts to walk and orders us, to walk silently aswell, and gets mad at me, because i rush into B (and get the entry frag).
Map: Cache, T side. The russian guy says rush B and as soon as we reach B Main, he orders us to walk. doesn't throw a smoke, to try to sneak into the bombside, just walks end gets picked off, because he's too slow and the CTs can get into the defending positions. Sometimes he even started to camp outside of B, as a "rush".

So what does rush means to the russian players, and how can i convince them, that this "rushwalk" is irrational, and counterproductive?

Sincerely,
Fellow CS:GO player

*Edit: Since most of you guys think, this is a joke. no. I'm totally serious. I want to know why russians use this "rushwalk" tactic, if it never worked.
