A pint is a unit of measurement. A US liquid pint is the same as sixteen ounces — you could order a pint of iced coffee at your local cafe, but it may just confuse the barista.
The term pint is more familiar in Britain than the US, although it's used to measure goods in both places. If you order a pint in a pub, you'll get a large glass holding one fluid pint of beer, and in the UK you can also buy pints of milk. British pints are larger than their US counterparts, though — both countries consider a pint to be one-eighth of a gallon, but an Imperial gallon (in Britain or Ireland) is larger.
