I'm not sure he could've picked a worse choice of words.

Jono on page 328
Improper words but the meaning is still valid.

Kid Cthulhu on page 328
Whoa, talk about berserk buttons!
Ash SMASH!

Two choices here:
1: Sam: "Wait... You're not saying..." *facepalm* "Oh. My. God."
2: They actually kiss.
I give it a 70/30 probability in favor of 1.

Oh dear, it was a kiss that started this mess.

...now that the obvious has been addressed; Why does Ash react so violently to a simple yes or no question? It isn't as if she was boy wearing perfume. Ash is a girl and it isn't that strange for young girl to wear a nice scent, especially for a special event like a wedding.

I love Sam's ninja reflexes calmly catching Ash's arm.

@Wally, At her age? Not really. Given her feelings regarding make up and dresses, it's not really surprising.

@Toothless Gus: Not in my experience... my wife and I raised 2 daughters, four years apart (with a son in between). There was no problem getting either of the girls into dresses, makeup, and perfume from pre school on. We had more of a time trying to get them to dress down, wear jeans and such for play. Of course in Australia, things might be different than here in The USA.

For the same reasons Ash isn't wearing a dress. And for that matter, why Charlie might be equally upset to get caught in girl perfume. "Girl" things have a lot of gender constructs and stereotypes associated with them that many girls nowadays want nothing to do with.
In other words, that definition of "girl things" is getting outdated and girls find it offensive/demeaning.

Upbringing has a lot to do with it, and this certainly isn't a universal thing.
The short answer is "tomboy". Ash is a tomboy, which is basically defined as girls who reject girl things and do boy things. The word has been around since the 1550s, and the concept is probably much older.
You could argue whether tomboys are trying to maneuver social stereotypes and gender roles to be seen as higher status or just don't care about outside pressure and are doing their own thing, but that's kind of a moot point because they exist and act like this. The grander societal implications are a little out of scope of this comic or the question in this thread.
