look up any word, like sex:
 
1.
In general, telling someone they will be going to hell to burn for a supposed amount of time, weather used as a threat or for their own belief that the soul of someone is in danger(in their eyes anyway)
Telling a prostitute she is going to hell unless she changes her ways. is a form of Hellwishing.

Randomly telling someone they are going to hell for no reason other than you don't agree with their religious choices.

These are forms of Hellwishing.
