Tip of the day for the middle aged

The other day I overheard a conversation between two average looking businessmen that ended with one of them all of a sudden high-fiving the other while yelling "mad props!" What I learned: never, and I mean never, use this term in either verbal or written speech. It's the language equivalent of that 50 year-old guy with the thinning hair, a ponytail, and a soul-patch who thinks he looks cool but really just looks like a 50 year-old guy with thinning hair, a ponytail, and a soul-patch.
