It's a gimmick at the collegiate level where an athlete can have longer eligibility to play if they practice with the team, but not play in games. So you'll have five-year seniors playing at the other end of that time.
A redshirt freshman is a sophomore that didn't play during his freshman year. It's his "freshman" year of football, but his sophomore year of college. And like LT said, if he stays with the program, he will be in his fifth year of college during his "senior" football season.
It gives scrawny freshmen a chance to learn the game at the college level and bulk up. Also, if you really expect the guy to have a degree when he leaves, 5 years is not that uncommon no matter what these days. Throw in the time sink that is college football and it really takes the full 5 years.
This thread is supposed to be about confessing your ignorance, not telling me what a red-shirt freshman is. That was merely my example, to get things going. And Alabama totally kicked Clemson's ass. So there. SEC football r00lz, suck it, haters.

My ignorance: I can never remember what "sanguine" means.
And lest this revelation seem purely theoretical, I live with someone who uses this term on a regular basis. Today, in regards to a lizard. And I know that I think it means one thing but it actually means the opposite, but I've lost track of what I think it means, so I can't remember what the opposite would be.
I don't really know how the horn works on my bike. I was going to fill it up with the bike pump, which is how you're supposed to do it, but the trigger is kind of attached to that - the fill valve. You press the trigger and holy fuck it's loud - 115 decibels, loudest bike horn evah. I was biking down by the waterfront and set it off and scared the poop out of this rat in the bushes, which was fun - little guy jumped four feet. It's late, and I don't want to touch the horn or even look at it because that'd wake, well, everyone. Also... the volume control switch. I can't set it because the thing's too loud, and there's no indicators showing "kinda loud", "freakin loud" or "I'm bleeding here!" And I don't know how it really works.
