If you want to hear what it sounds like when a friend realizes his buddy cut off his penis ... you've come to the right place.
TMZ has obtained the 911 call from an incident in April, when rapper Christ Bearer -- affiliated with the Wu-Tang Clan -- jumped off his apartment balcony after cutting off his junk.
Christ Bearer's friend told the dispatcher he didn't see the cutting but did see the rapper jump. The friend initially tells the dispatcher the rapper might be dead, but then you hear Christ Bearer scream bloody murder.
Then it gets crazy ... the friend says Christ Bearer ran upstairs to the apartment and tried to get in, and that's when he noticed the carnage.
You gotta listen ... it's unbelievable.
