Red-RazzleBerry What is you guys favorite clean word and why? Swear word and when?

"Fudge because... Well... Fudge," David shrugged.
"Nice," Jack chuckled.
"Thanks?"
"I do not have a favorite clean word," Jack shrugged.
"Swear words... Um... I don't really swear..." David sighed.
"Huh, I do not think I have ever heard you swear," Jack mumbled.
"Exactly, so I don't think I have one," David explained.
"Understandable, I am partial to words such as damn and hell, one I use on a regular basis around here, and one represents my life... A living hell," Jack chuckled.
"Do you really feel like that?" David frowned.
"Most of the time," Jack shrugged.
