One way street 

When you don't get treated with the same amount or love or respect. One sided affection.

I used to love this girl Cristina but I eventually found out it was a one way street kind of love.

One Up with a Topper 

When a one up just isn't good enough and some "icing on the cake" is deemed necessary. Occasionally, the topper is topped without rebuttal. Both the "One Up" and the "Topper" are unusually suspicious.

Me: I had great seats for U2.

Friend (One Up): Yeah, well I had front row.

Friend (Topper): And, I got backstage.

Friend (Extra Topper): Oh yeah, the tickets were free!

Me (to myself): Unbelievable, another One Up with a Topper!
