Real life is where events happen without a computer or the Internet as a primary component. It is often used as the antonym of "online".
Boylovers occasionally use real life to signify the part of their life that they present to non-boylovers, regardless of whether it involves on-line or off-line activities. Thus, experienced Internet community members will wonder at common usage such as "real-life e-mail address".
In writing, one often sees the abbreviations RL for "real life" and IRL for "in real life". As a matter of practice, "IRL" is often found in cases where "RL" would actually be more appropriate, as in the sentence "We had an IRL meeting".
