Wetting her pants wasn’t enough to crudely imitate Applejack. Rarity took it even farther and messed her pants as well. Quite noisily, as a matter of fact. Applejack didn’t know which shocked her more, that Rarity wet and soiled herself, or that she thought she (Applejack), or farm ponies in general, would do such a thing.
 
Rarity sure felt foolish once she returned to her ladylike self. (See the next one here)
 
I got the idea from a comment on my earlier picture of Rarity wetting herself, and I couldn’t resist, the idea was so appealing to me. Though of course anyone not into this will find it disgusting or offensive, in which case, ignore and go onto a cleaner picture.
