Respect and courteries rendered for an ethical, proper action someone did that is further warranted through facts, politics or other mitigating circumstances deemed necessary.
In a recent Man Tracker show on Discovery two beautiful, young, ambitious ladies lost to Man Tracker at 2.9 miles from finish but he still gave them all due propers, respects and courtesies for not being quitters(losers) in the face of adversity to reaching for their higher potential.
Proper is actually a word you can use all by itself, you can just expostulate "Proper!" and it means something similar to "Wicked!" or "Excellent!" or "Cool!". It is an exclamative word. If something totally cool or awesome happens you just say "Proper!" and it means the same as "Awesome!" or "Cool!", but it is much newer and fresher and better and longer-lasting than those words. Its literal definition is "Perfect". Say this if you want to not only be with it, but way, way ahead of it. Proper.
