A port-a-fort is a poggers epic metal tower that can be carried with you in frotinet. When you throw down the port-a-fort a long sexy metal tower will be placed down and you can go inside and go on bouncy tires to have epic roof sex and kill ugly curry munchers
Me: I just killed some cunt in my port-a-fort
Friend: Wow he must have been an ugly skank whore cunt dick sucker
