I've occasionally punned with variable names. One I like (and I forget where I first saw it) was %cornedbeef. (corned beef hash). I've been do to do { ... } until $cows_come_home; or { ... } until $hell_freezes_over; for nigh-endless loops.

When I'm not being creative, I find myself occasionally using junk variables like $stuff, $stuf, $stuph, $morestuff, $yetmorestuff, $evenmorestuff, $toomuchstuff, so on and so forth.
