To be considered as an additional definition of "Kappa Kappa Psi" and •not• intended as a derogatory dig at the honor society of the same name.

The sound —first heard circa 1981— made by someone using a PC keyboard when they forget (for the umpteenth time) that the shift key, with Caps Lock engaged, doesn't behave like a typewriter's caps-lock/shift combination.

Of note, this was Bill Gate's first "productivity improvement" (of many, so-called) lofted on an unsuspecting public.
The kAPPA kAPPA pSI is most likely to be encountered when opting to let fingers fly over the keyboard while typing a familiar phrase, before realizng caps lock is engaged:

(starts typing) "tHE qUICK bROWN fOX…"
<sigh>
"Damn you Caps Lock!"
