"Tiger blood" entered the pop culture lexicon when the hard-partying actor Charlie Sheen claimed the substance in a 2011 interview. It's also a brand of anabolic steroids, the name of a snowball flavor and a metaphor for the resiliency of LSU athletes such as Derrius Guice.
Last week, the phrase was uttered in the U.S. House of Representatives for perhaps the first time, when LSU alumnus Steve Scalise (Class of 1989) made a triumphant return to the Capitol. Shot and gravely wounded 3 1/2 months earlier, the Jefferson Republican spent 16 minutes at the rostrum thanking God, his wife, his colleagues, his friends and many others for his recovery.
