J. Random Loser. The names JRL and JRN were sometimes used as example names when discussing a kind of user ID used under TOPS-10 and WAITS. They were understood to be the initials of (fictitious) programmers named "J. Random Loser" and "J. Random Nerd". For example, if one said "To log in, type log one comma jay are en" (that is, "log 1,JRN"), the listener would have understood that he should use his own computer ID in place of "JRN".
