Awful
It's animations like these that make me lose respect for sprite flashes. That was one lame joke after another. Terrible. You're on Newgrounds and you can't even make a decent cock joke. You're doing all the silly things that most sprite artists do: Black boxes for widening mouths, taking spelling/grammar for granted (Or using excessive punctuation in an effort to make it funny), and overall laziness. I'd like to say that if you took the time to clean it up, this would be good, but you'd also have to make better jokes, and frankly, I don't see that happening.
I'm going to agree with Digimaks. Grow up. This may have been funny to me back in 7th or 8th grade, but now it just makes me roll my eyes and lose hope for sprite flashes. Sex and homosexuality itself isn't funny. It can be made funny, oh God yes, but just throwing it out there for the sake of doing it doesn't cut it with the older crowd, sorry to say. Better luck next time.
