all-elbows adj.
[MS-DOS] 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.
