What it does
The user bites their target and shoots large doses of stored chakra directly into the target. This has many practically purposes. It can jump start downed shinobis like an adrenaline shot, give a boost to allies that require more chakra, or it can even be used offensively to force way too much chakra into the enemy's body.
Description
Too much chakra injected directly into the body can cause chakra overload, a condition that gives the victim an adrenaline rush depending on the chakra nature forced upon them. Results vary between intense pain, death, the inability to control your own body, destruction, possession, all sorts of nonsense! Some people even feel drunk!
