assuming fluffhead is the kids surname,
how about 'Gimmesum'?
or 'Reacharound', reachy for short?
Go all ancient latin n stuff- 'Analingus Nolikeus'
be topical- 'North by northwest on a south easterly heading'
sure its a mouthful, but the kids trendy right outta the womb & that shit is priceless.
Now Stu is an awesome option, just with a slight adjustment.
'STFU'- now thats a boys name!!
Can be somewhat confusing when talking to others.
Especially when you use his full name, cause you are cranky n stuff.
But my votes for
'Shut the Fuck Up Fluffhead'
now theres a name of power & authority.
ok then, I named the kid, moving on to the next item.
You guys need to come down under so we can make me little 'shutty fucky fluffy's' godfather.
I aint coming over there, your guvmint is crazy.
you can thank me when you get here.
