"Disgusting." (deadpan tone) and "Kimoi." are not as different as you'd like to imagine.

The 2nd paragraph was calling you a weeaboo without saying "weeaboo." Throw in random Japanese terms when it is appropriate, as in when there is no English analog (honorifics, lexicon terms...there's really not much else). Other usage tends to make you look like a...weeaboo for lack of a better term.
