[MS-DOS] adj. Of a TSR (terminate-and-stay-resident)
IBM PC 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. See rude, also
mess-dos.
