{maqDar} comes from (DS9 "House of Quark") :
A drunken Klingon in Quark's Bar has nearly
passed out and is out of money but wants credit. Quark goes to
show him out. He bangs the table several times with a mug to
waken the man, then boldly says, "My name is Quark!" Kozak
awakens, growls stands up shakily, saying: "You dare to talk to
me like that? You pathetic *mak'dar*!" He
then draws his knife and attacks Quark.
