Too much time on his hands - Boing Boing

"That guy has too much spare time" is one of the most odious, intellectually dishonest, dismissive things a person can say. It disguises a vicious ad-hominem attack as a lighthearted verbal shrug. The subtext of the remark is that the subject's passions -- this remark is almost always directed at someone engaged in some labor of love -- are so meritless that their specific shortcomings don't even warrant discussion.

The man has a point. Resolved: I'm never going to use that phrase again.
