jargon Said of a TSR (terminate-and-stay-resident)

mess-dos program, such as the N pop-up calendar and

calculator utilities that circulate on BBS systems:

unsociable. Used to describe a program that rudely steals

the resources that it needs without considering that other

TSRs may also be resident. One particularly common form of

rudeness is lock-up due to programs fighting over the keyboard

interrupt.
