Yeah... in TX, swearing comes naturally as we don't really mince words when it comes to certain things. However, it fits really well into everyday conversation and it doesn't feel like it is overdone... people just tend to have strong opinions here and we do have more than a few ways here to effectively express when we think someone/something is full of BS... the older, the more creative/craftier and blunt we are about it...
However, nothing is more embarrassing than someone who descends into a total tantrum full of swear words and other self-absorbed nonsense... it just looks very bad and like that person has become unhinged.
Just some random thoughts.
