[common] Said of someone who willfully does the {Wrong Thing};
humorously, if one uses a feature known to be {marginal}. What is
meant is that one deserves the consequences of one's {losing}
actions. "Boy, anyone who tries to use {mess-dos} deserves to
{lose}!" ({ITS} fans used to say the same thing of {Unix}; many still
do.) See also {screw}, {chomp}, {bagbiter}.
