Usually the term is a prefix.
In the subcontinent and beyond if the term Semi is a stand alone utterance, it means you know what. Semi-crack.
There is an arithmetical paradox here. The paradox makes half more than half. This is how it is:

You look perfectly normal in the stands of the cricket stadium, but once on the bar-stool you are not full no matter what and how much you fill.
Which one would you love to be called?
