To punch someone in the arm very hard causing them to experience much pain. Exessive punching may cause black or purple colored bruises on the arm region. Two(2) dead arms may be given if the person recieving the dead arms flinched when the puncher began to punch the first person. This situation is called "two fer' flinchin'".
Nick gave Chatty a dead arm after he made a stupid joke. Nick gave Chatty a second dead arm after he took Nicks seat. Nick continued giving Chatty dead arms for each time Chatty made a stupid comment resulting in Chatty's badly bruised arm. Chatty is in much pain...ow.
