mcslippy

(spelt mcslippy or mcshlippy) rlly cool word, it means whatever you want it to mean. It could be a compliment or the most offensive word in the dictionary. The best part is, no one can interpret it as anything else because it only means what you want it to mean. (Mcslippy is a negative intent, Mcshlippy is a Mcshlippy intent.)

"woah dude, your being really Mcslippy right now."
"what does that even mean"
"....."
