[Usenet: very common] Abbreviation: You Have
Been Trolled (see troll, sense 1). Especially used in
"YHBT. YHL. HAND.", which is widely understood to expand to
"You Have Been Trolled. You Have Lost. Have A Nice Day". You
are quite likely to see this if you respond incautiously to
a flame-provoking post that was obviously floated as sucker bait.
grue n.
[from archaic English verb for `shudder' as
with fear] The grue was originated in the game Zork (Dave
Lebling took the name from Jack Vance's "Dying Earth"
fantasies) and used in several other Infocom games as a hint
that you should perhaps look for a lamp, torch or some type of
light source....
