a shitwafer is a slightly built shithead. this person is likely very weak physically, but has a big mouth that spews mostly bullshit. they are delicate and hollow.
A portmanteau of the English swear “shit” and “Squidward”, the name of a character on SpongeBob SquarePants. Typically interjected in situations of surprise or shock, however can also be used as an insult.
“Dude, your car exploded!”
“Holy Shitward!”
“Such raw talent cannot be wasted behind this register!”
“...Get back to work, Mr. Shitward.”
That one shit that drops so hard and so fast (almost Matrix style) that before your asshole has a chance to close you get a nice splash of ShitWater back in your hole!
