"Yo Momma" - for all the right/wrong reasons (especially on the app and their system - "Yo Momma's been booked in for a service", "Yo Momma needs a new tyre" etc. etc.)
I tend to go up the marks on tech, for example the PCs I've built are all called GIZMO - current one is called GIZMO MKIV. May be swayed to call the car a variant of Gizmo.
