Instead of "intruding" in someone'
s space, one "inturds" in someone'
s space by making an ass of himself/herself in the process.
Having not agreeing to his wife asking for a
divorce, he inturded into his wife'
s papers and personal affects.
Or (thanks to my colleague):
There once was a
man named McBride,
Who fell in an outhouse and died,,
And he had a brother
Who fell in another,
And now they're inturd side-by-side
