You really are one mean mutha fucka aren't you!!
Have you no shame? These people have been through the trauma and pain of losing a limb just to have a cunt like you hurl sick and twisted insults at them? Shameful!
Disability is NO LAUGHING MATTER! We must end all this making fun of people just because they're not as able bodied as us! You should be ashamed of yourself - you're a disgrace!
Anyway, in answer to your question... "Oi! Stumpy!" usually gets 'em agitated.
Now, get some help you sick fuck!
