What do Brits means when they say "perving around"?

A friend mentioned her British girlfriend talking about drinking and "perving around the pool." What are the possible meanings for this? I gather from my friend's story that this Brit wasn't a pervert, as the word might imply, but was it an ironic usage? Anyone from the U.K. want to chime in?

It's not perving around, just perving, but it's an activity that, like drinking, might well take place around a pool.

It is related to pervert, but used in a self-deprecating way - your friend just means enjoying the sight of attractive bodies on display. A synonym would be leching (from "lechery", again a self-deprecating use of a term with stronger connotations).

There's an exact old word equivalent to "perving" which is still in use in the East Midlands. When someone is peeping slyly, he is said to be "chiking",and is called a "chiker".

That is a long "i" sound, and the word is probably better represented "ch-eye-ker" for pronunciation. The spelling I give is from printed usage I have seen. There is a short story by Alan Sillitoe, titled "The Chiker".
