From the infinitive 'to sible' (pronounced 'sibble'), meaning to perform some form of sexual act with another persons brother or sister (preferably younger for greater novelty value...though not TOO much younger). For clarity in use, the given example would mean that to sible 'her', would be to sleep with 'her' sibling.
'Dude, I would totally sible her...soon as her younger sister's street legal of course.'
'For sure dude! I'd give her the sibling of a lifetime.'
'For sure dude! I'd give her the sibling of a lifetime.'

In general, younger siblings are slightly more annoying than older ones, although in general older siblings are meaner and stronger so beat up the younger one.
