Swears are fun. But if you use them without creativity you can give people the impression that you are stupid or even worse...boring. One also might want to have on hand some pseudo-swears words that sound like swears but are in fact not.
(conveniently sounds like a swear)
You Basstart! Have a Basstart.
Warning: do not leave Basstarts in your home or it will smell like a waste treatment plant. Do not feed to dogs, as they will become incredibly gaseous.
