Have Ты ever been in a situation when something comepletly disasterous happens and Ты say "OH SHIT!" well, when a moment like that happens, Ты cant stop it from happening. when there is an "oh, Shit" moment, well Ты say oh shit because Ты cannot believe what is happening, and also believe that there is no way of stopping it. when a бык jacks its horns right into your sensitive area, well it just happens so fast that Ты cannot believe it. and when a лодка turns over, Ты cannot stop that,OVERBOARD!!!! When things like that happen, and worse, well its just at that moment или witnessing it, that Ты say, OH SHIT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!=)
