I like these from the Belorussian, Vika :

>pizdziczy ( adj )
extremely talkative Ex.: John vel'mi pizdziuczy bo jon moz*a pizdziec' pjac' hadzin biez perapynku. John is extremely talkative because he can speak for 5 hours with no breaks.

pizdziuk ( masc. noun, pl.: pizdziuki )
one who talks too much Ex.: John pizdziuk bo jon moz*a pizdziec' pjac' hadzin biez perapynku. John talks too much because he can speak for 5 hours with no breaks.<

Is pizdziczy pronounced pizh-zhi-zhy?
