cursor dipped in X
n. There are a couple of metaphors in English
of the form `pen dipped in X' (perhaps the most common values of X
are `acid', `bile', and `vitriol'). These map over neatly to this
hackish usage (the cursor being what moves, leaving letters behind,
when one is composing on-line). "Talk about a nastygram
must've had his cursor dipped in acid when he wrote that one!"
