reciprocality 

Another word that Donald Trump pulls out of his tookus when he is attempting to sound intelligent.

Reciprocality would evolve if our President would step down and admit he is unfit for the job.

Friendship Reciprocity Ratio 

The friendship reciprocity ratio, or F.R. Ratio, is the ratio representing the unwritten friendship law that the sum of x-friend's purchases for y-friend should be equal to, or as close to equal to, y-friend's purchases for x-friend. The closer to "0" this ratio is, the more substantial the friendship. Any friend who is significantly negative in this ratio is a shitty friend.

Dave- Dude, Greg "forgot" his wallet again. Had to pay for his lunch again. Not to mention I bought him an Audi for his birthday last month and all I got was a misspelled "Hapie Berthday" on Facebook today.

Nate- Greg is a shitty friend. What's your guys' friendship reciprocity ratio at now?

Dave- I think he's got our F.R. Ratio down to -$3,000,000 now.

Nate- Wow dude, what a piece of shit.

Facebook Reciprocity

reciprocity 

The expectation, knowledge or at least hope, that somewhere down the road you will be repaid for an action you were responsible for. In negative terms, it's revenge.

Getting five bucks for mowing the lawn
