all-elbows

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}.
