Heidi Wicks's definitions

douchebag

Douchebags are typically smug, and exude self-confidence. However, rarely are they actually self-confident, but are usually more likely lacking self-confidence. There are the rare breeds that are so deluded that they believe they are cool, when no one else thinks so. In this case, they are not lacking self-confidence, but are just deluded.
