By definition all hookers are pests. But not all pests are grubs. Back in the day, a coach of a junior team would always pick out the least attractive kid, (yeah, the one with the crookiest melon) and make him hooker on the well acknowledged principle that his mother would be the mom least likely to complain about his "looks" when he got home after a game. Now they pick the nastiest little bast... they can find. However having said that, Ballin of all the thousands of hookers I have watched over the past 55 years is the least pestlike and grublike I have seen, at times I have even thought he would be kicked out of the hooker union. Possibly tunks is using a more literal interpretation of the word pest as in meaning he keeps making 50 tackles a game.
