Swearing happens. Do it appropriately if you must.
I swear when I die for the 10th time on the same spot in Mario Bros.
I swear when I have 1 ton of wood w/ trailer dropped on my foot.
I think that constant swearing gets rid of it's effectiveness. When I swear around my friends, they know I'm ticked off. People that constantly swear, as already mentioned, are quite funny for this reason.
5 Rules for swearing:
1. Don't use the Lord's name in vain.
2. Swear around people that could care less. Not your fiance's dad.
3. Don't do it constantly.
4. Swear online for effectiveness. Like when someone tells you that you're dumb. Attack back with 'Well atleast I don't sound like a ::DOLPHIN NOISE:: ::DOLPHIN NOISE:: ::DOLPHIN NOISE::.
5. Swear when you mean it. Not cause you dropped a straw at McDonalds. Ohh ::DOLPHIN NOISE::....who cares!?! Grab another straw, ::DOLPHIN NOISE::!
