look up any word, like pussy:
 
1.
Getting shot ('poisoned') by a 7.62 bullet.

The origin is unknown, but its military slang popular amongst servicemembers (especially The Marines/Army) that have been deployed to Iraq or Afghanistan.

The 7.62 refers to the standard caliber of round fired from the AK-47 and its many close relatives. In contrast, the US fires a 5.56 round.
Yea, but I'm not anywhere near combat, so my odds of getting 7.62 poisoning are slim.
