Well you could always use your favourate porn stars name
like Nikki-Nova Jenna-Jameson Daytona_Rains
or for your barb BillyBoB-Breaker Ben_Dover

But u could always make your own porn star name by using your pets name & your mothers maiden name
so my cat is called TABBATHA
& my mothers maiden is TAWNY
my pornstar name is Tabbatha-Tawny
