Wikipedia says this:
The word "crap" is old in the English language, one of a group of verbs applied to discarded cast offs, like "residue from renderings" (1490s) or in Shropshire, "dregs of beer or ale", meanings probably extended from Middle English crappe "chaff, or grain that has been trodden underfoot in a barn" (c. 1440s), deriving ultimately from Late Latin crappa, "chaff".
That sums it up beautifully... I feel as though I have been trodden underfoot in an effin barn! (prob. look that way too , today.)
So - sweet blog friends - I leave you with some Mc - Isms... I hope you enjoy this as much as I did! (compliments of www.wikipedia.com)

The characters often say "seriously", usually at the end of a sentence, as a question or as a pronouncement. Krista Vernoff is credited with the introduction of the catchphrase, "seriously" into the dialogue of Grey's Anatomy episodes. Series creator Shonda Rhimes says that Vernoff used it frequently in the writer's room, and "said correctly, it can convey sarcasm, dismay, disbelief, a sense of moral and ethical superiority, and gentle chastising punishment, all at once."
 Sexually-Related Terms
Network censors make it difficult for writers to use sexually-related terms such as the word "vagina", which has led to several euphemisms for female genitalia or other sexually-related terms. These include:
"va-jay-jay" (Season 2 - Episode 17: As We Know It [Part 2])
"good girl" (Season 2 - Episode 24: Damage Case)
"hoo-hoo" (Season 3 - Episode 21: Desire).
In addition, network censoring caused the writers to use the phrase "cashing in [her] V-card" (Season 2 - Episode 27: Losing My Religion)was used as a euphemism for losing one's virginity.
Meredith's dialogue involves her talking and using well-known phrases but she trails off at the end and replaces the last word with "whatever".
 Season 3
"There are rules to this friendship thing or whatever" (Episode 7: Where the Boys Are)
"There's too much water under the thing or whatever" (Episode 7: Where the Boys Are)
"You are not my knight in shining whatever" (Episode 15: Walk on Water)
"I had a near-death whatever" (Episode 18: Scars and Souvenirs)
