Bike-Bum

When you cycle on a bicycle that has a REALLY hard and uncomfortable saddle, you'll be left with an annoying pain your backside that you will only feel when you sit on something, even the comfiest seat will hurt thanks to this hidden pain in your bottom.

It takes roughly 24 hours of not riding on that saddle again for it to go away. Depending on how loing you were cycling initially.
Dude #1: Why are you sitting so weird? You're on the single comfiest couch in all existence!

Dude #2: Got Bike-Bum. Even this heavenly sofa feels sore thanks to that cursed hard saddle!

Dude #1: 'Bummer!'

Bum Nuts

What your dog leaves on the patio. Normally firm, well formed stools that bear an uncanny resemblance to walnuts, or pieces of chopped sausage.
