I just heard a criminal attorney say the word "looksie" on national TV. As in, "We should take a little looksie at that issue." When you say the word "looksie," you've voluntarily surrendered your credibility, and, if you're a man, you've surrendered your man card.
ADDED: A commenter has said that they think it's called a "look-see," like it's short for "look and see." That makes it a little better, a little more adult-sounding. What do you think?
