A thrifty individual whom:
1) Specifically buys items at reduced price, honing in on sales or perceived "bargains."
2) First on the scene to receive free items, naturally flocking to such occurrences.
3) Has mastered the art of manipulating the generosity/good will of others for personal gain.
Individuals who possess this behavioral trait are quite often difficult to identify. "Mr.Jackson is such a jewhawk, he is always searching for a bargain!"
