As a kid, we used to say "Pucha" a lot (Peru/Bolivia). It means (or it meant) something like "Holy Cow!" or "Damm". Whenever something happened in an extreme way. Like if you put your finger on a hot oven, you would exclaim "Pucha" (Damm), or "Pucha, hombre !" (slightly more emphatic than "Damm") Anyone familiar with this word and is it used in all Spanish speaking countries?
