A girl's close male 'friend' that she sleeps
with when her self esteem
is a bit low. Usually an ex. The guy that every significant
other should beware of any time he screws up even slightly. You'll know which one he is because she'll talk about him like you'll never
be quite as charming/good in bed/sensitive/etc. as he is.
"Her boyfriend looked at another
girl at the mall, but she felt better after she hooked up with
her Josh." or "Hey man, that
guy's her Josh... when she starts hanging out with
him again you might as well just
pack your stuff."
