Proverbs 4:24 Keep your mouth free of perversity; keep corrupt talk far from your lips.
I know I will sound like an old man by saying this – but what comes out of your mouth does define you in many ways!
It is not nice to listen to a young person shout and scream obscenities at others. It is not nice to have to listen to anyone say such things.
Saying bad stuff seems to switch something in your brain which then somehow convinces you it is OK to do such things… it’s not! No matter how many times you say it!
