the act of using your iphone without a case. the term freeballing has meant putting on pants without underwear for years along with "going commando", but in this day and age it's necessary to have a set term for something that people do every day. can be used for non iphones but they are the most fragile phones and will crack easier than others.
Dave: John loves freeballing his iphone because he says the iphone is too beautiful to be protected by any case.
Adam: he said the same thing about his pants last week!!!
Joseph: Chris loves flexing, but he never freeballs because he drops his phone way too much when in the case.
