Considering my name's just me working with what is essentially a misspelling of my actual name, I would probably be a little bit confused. Eh.. I tend to make up nicknames for people every now and again anyways. I find using long names way too formal.
The line of names, if you're wondering.
Patrick -> Pat -> Patty -> Oaty -> LordOaty: Prince of Breakfast Cereals
There isn't really a good story for how I came about such a name, one of my mates just said it once in chat and I was like "eh, that works".
