If he wants to mess around with your tire then get him, back with screwing with his tires or his car locks ... For his tires, if you have a valve stem remover remove the valve's stem but first apply a lot of super glue or epoxy around the threads of the stem .... place your finger tip over the stem to help keep the air from escaping , wear some rubber gloves , then place the tire cap back on... hold the cap in place with your finger until the glue dries... reapply some more glue around the edges of the caps. this should hold for a while until the ******* drives off some place
. You could also do this to his bike if her cycles.
If no valve stem then just use Epoxy or supper glue on his car door locks, Inject some in the locks if you do it right you can seal them shut .
You got excited over this didn't you
