words that irk me

In construction, I have known guys that use and fuckin frequently. It sounds so ignorant.
Over here at this wall, you need to run a row of blocks and fuckin at 28 inches to center......and fuckin six feet and down for the cabinet mounts and fuckin A-34 brackets at all 4 corners.
WHAT does And fuckin add to the sentence ???
It makes you sound all manly:D
It's expected on a construction site but I was cringing when a fellow worker was talking to a young woman from the general contractor was on site. F bomb was coming out every other word, and she was just smiling the whole time. Some guys don`t realize their doing it. Worse is going with a crew to lunch in a restaurant and the F bombs go flying.
Embarrassing, some guys just don`t have any couth.
I was bad when young but trained myself control.
