I can't spell for shit.
Was in a hurry.
Actually, that is spelled correctly, "for shit" unless you were trying to say foreshit, which is that little bit of gas and leftovers from the last shit that finally has its day, just before the REAL shit crowds its way out.
It could also be a warning to non-combatants down range for when you are flinging shit at an enemy. It would only be courteous to call out, "FORE! Shit!" as you hurl.
However, if you are numbering successive shit, then it goes One shit, Two shit, Three shit, Four shit, etc.
It may be confusing, but counting shit is more complicated, because you must pluralize the word "shit" after you count more than a single shit, as in one shit, two shits, three shits, four shits.
Hope this helps.
