Aug 11 Word of the Day
A phrase to describe someone who is cognitively degenerating. Synonym of "going off the deep end". Can have varying degrees of severity.

Reference to the song "Hey You" by Pink Floyd. The line "and the worms ate into his brain" makes no sense in an otherwise linear and literal narration throughout the lyrics.
"My boyfriend has a total case of brain worms. He told me the cat was bugged so the Feds could listen in on us having sex..."

or

"You totally stumbled over that entire sentence. Can't speak English all of a sudden? What, do you have brain worms?"

Game: The act of killing an enemy that was weakened by another member of your team. This action will often upset your teammate and should be done with caution. Can also be used as a noun. (kser: kill stealer)
In-depth Version: It's 2 vs 2, you and your teammate and 2 enemies. Both of you have a specific person to kill.

Say your enemy is weakened and you only need more hit on him before you can gain exp/gold/etc.

Your teammate's turn is before yours, and on his turn he kills YOUR enemy. Congradulations! You've just been ksed.

KS is from the Chinese term kong shu (both 1st tones), basically meaning feeling very empty. Absolutely running on fumes.
