He's going completely mad.
Why the fuck is the Night Star canon including the entire events of Chris being trolled? Isn't Night Star supposed to be in Equestria? Does this mean everyone in the Pony-verse is aware of Chris, his bent quacker, and the CWCki and even have seen the Julay tape like it came straight from the movie American Pie?
And apparently he's mentioning Mia Hamm... and not in good light, calling the experience a "Nightmare."
Haha, he now considers his first time having sex a nightmare.
@Marvin and others are right when they say Chris has a shit libido.
