Comments indicative of this behavior range from the mild/moderate:
~"Pshaw. It can wait until tomorrow."
~"I don't weigh that much."
~"I can pay for this next month."
More extreme cases make remarks such as the following:
~"I'm not a hoarder; I'm a collector."
~"I can so rock this Speedo."
~Or if you're OJ Simpson, "I'm still looking for the killer, seriously."
~Or pretty much anything Lindsay Lohan says.
~Or all those enablers/parents of American Idol wannabes.
~Or especially those trying to justify their participation in this train-wreck.
~Or if you're me, "I totally look like Russell Crowe."
