look up any word, like tinder bombing:
 
1.
A wheelchair buddy is one you will go to the same retirement home with where you will sit around all day playing bridge, talking about old times and racing each other down the hallway while having a laugh.

In essence its a friend for life!
Your my best friend! You have made the wheelchair buddy list!

Jack: Thanks for letting me stay over!

Joe: Everything for a wheelchair buddy!:)
