Half calf can be one of two things. One thing can be when you are trying to cut back on straight caffiene coffee so you get half decaffe half regular or when your penis has half a boner but its not all the way there , so its also half soft.
Mom:yeah ive been having way to much regular coffee lately
Son: why dont u get a half calf?

It is where one person thinks his or her calves are the best..

When in fact it is clearly one sided that the guys are better and look so good that they may be thought to be fake
Guy: my calves are the best
Girl: no way I work out all the time and pay someone .. I have the best legs ever..

Guy: UM why u freaking out and stomping ur foot ..my calves rule ...

Girl: OMG OMG OMG NO MY CALVES ARE EVERYTHING W/O THEM I AM LOST I LOVE MY LEGS... I AM THE BEST I AM BUCCI.
Guy: we should have a calf off

Sexier and easier to pull off than a thigh gap....this new aged form of hotness lies between the gap of the calves instead of the thighs. Its presence indicates wealth and beauty and is so seductive that many are starting to notice....
Brandy's calf gap is so hot right now!

Did you see the calf gap on that one! Its the sexiest I've ever seen!
