Drugs can really mess up your perception of reality. They can make you think you’re quieter than you are, better looking than you are, or in this case stronger and a better fighter than you are.

A man who was strung out on meth decided to mess with the wrong girl and when her dad came out, the drug addict decided to try and fight the dad. What he didn’t know was that her dad is a Black Belt in jiu-jitsu.

Black Belt Christopher Guarino was called on to handle the allegedly drugged-out intruder in his Florida neighborhood after the unidentified assailant reportedly bullied an elderly neighbor and then exposed himself to Guarino’s teenaged daughter.

The video, narrated by the daughter, shows Guarino working to deescalate the situation unsuccessfully as he shows his hands and says “I don’t want to fight you” to the amped-up, punch-throwing assailant. When de-escalation doesn’t work, Guarino takes the obviously altered man to the ground, gets into heavy side control, moves into mount…and then doesn’t take it any further. No ground and pound. No violence.

Guarino, a registered nurse and former Gracie Barra instructor, shared the video to his social media as an example of how to show restraint while defending one’s family. Police were called and no unnecessary injuries were sustained. (JiuJitsuTimes)

“You can’t just f*** with people!” Guarino tells the man at the end of the video.

This is one reason why drugs are so terrible. They hinder you from making any real rational decisions. This is probably not something the man would be doing otherwise if he were not on meth, but meth can have that effect on people that makes them do and say crazy things almost as if they really don’t have control over their actions.
