A term used by many gamers (especially by or to imitate Russians) of CSGO (a first-person shooter). The phrase breaks down into 2 parts.
Rush B = B is a bomb plant site in maps in CSGO where the terrorists (a team) can plant the bomb to win. Rush B is, in some maps, the fastest to plant at, and therefore win. Cyka Blyat = A russian phrase, сука блять, to offensively address a prostitute. In this case it is used in distress to show annoyance or desperation, as would FFS. Used also to address friends in a jokey way, used non-offensively.
'Rush B Cyka Blyat' together is used to tell other teammates that the team should plant the bomb (objective to win) in the bomb site B (location).
All the definitions for this are related to a video game, which I admittedly do not play. One noted it as a typical Russian greeting. However, "cyka blyat" (pronounced like syoo-ka) means, literally, "bitch fuck." Not one single Russian I know would let you greet them like that unless you're "fuck my sister " cool with them. Suka is an extremely insulting word that frequently means bitch in a prison bitch context.
Yöb tvoyu matya, suka blyat!
Fuck your mother, bitch fuck!
The easiest way to win in CS:GO (Counter Strike Global Offensive) on T side. You take the bomb to B site and plant it. Make sure you do not stop running till you get there. Some good weapons to use when rushing B are, The P90 sub machine gun, The Russian made AK 47 rifle, and most importantly the P90 sub machine gun.
