It’s based off a nickname I’ve had for about 16 years now. Tigs Mcjagger (and yes I have the moves like Jagger).
She’d call me Tigger cause I used to be super hyper like Tigger, so since Fbook wouldn’t allow me to put Tigger as my name, shortened it to Tigs.
As for the last name, I’m not sure where I came up with that but it’s stuck.
