An unwanted substitute for big-boy curse
words that has made its way into your vocabulary strictly because
some kid who had his mouth
washed out at an early age says it unceasingly. Often comes
to replace, and completely eliminate the use of more powerful, and ultimately more satisfactory words. Can also result
in making you sound like an elementary school kid trying to act tough.
Can also be used in tandem with
"what the" to create "what the frick" which is a completely lame
expletive for situations when you really have nothing better to say.
