What Is “Giddy”?
If you’ve ever seen more than a few episodes of Seinfeld, then you’ll know that the character Cosmo Kramer will often say “giddy up” when something is awesome and/or is in his favour.
I see a lot of my own characteristics in Kramer, and I found that “giddy up” made me feel positive and happy.
So, it became a catch phrase of mine.
The definition of giddy can be found below. Although, I define giddy a little differently.
To me, it means awesome, great, fantastic, superb. Giddy up means almost exactly the same thing; sometimes I may use giddy up when accepting and answer from someone.
Example:
Me: What kind of candy are we getting?
Pierre: I have some Junior Mints and those liquid Starbursts you like.
Me: Giddy up!
I hope that explains my giddyness (yes, I prefer to write it with a ‘y’ rather than an ‘i’ like the film title The Pursuit of Happyness
