A penis comparable in size to a stick of chapstick. Most commonly found on Asian men, although not entirely limited to them. For instance many Ashkenazi Jewish men are known to have Chink dicks or quasi-Chink dicks. See Kosher Cock
for a full explanation. Strictly speaking a man of any race may be said to have a Chink dick, provided it is sufficiently small.
Yo son, I saw Tyrone in the locker room yesterday and he's got a small-ass dick!
But isn't he black?
Yeah, but he's packing a Chink dick!
