Quite frankly, it seems more like the latter here.
Jason proceeds to ask sexual innuendo-charged questions to Cady as his bonehead friends cackle in the background.
Its Regina who takes Jason to task for his behavior and embarrases him in a public fashion.

Maybe Regina experienced something similar a long time ago.
While hes technically available, since hes Regina Georges ex-boyfriend, this isnt as simple as it appears.
Cady didnt know that Aaron was Reginas ex until Gretchen Wieners (Lacey Chabert) tells her.
Unfortunately, Gretchen deceives her and tells Regina that Cady likes Aaron.
However, thats a topic for another day.
Yet, Cady didnt read between the lines.
Cady fails and Regina strikes back the only way she knows how: Hard.
Think of it as a teenage version of Brangelina and Bennifer.
But has anyone asked Regina for her side of the story yet?
Looking at the teens at North Shore, none of them are innocent victims inMean Girls.
This shouldnt be unsurprising to anyone who attends (or attended) high school.
Its Hell on Earth where decency gets flushed down the toilet and chaos reigns in every corner.
People do the cruelest things to each other and their behavior gets excused as theyre just kids.
Its a rotten and nasty place where only the strongest survive.
Regina understands this better than most.
She isnt afraid to roll around in the mud and get dirty when necessary.
She fights and claws for her own survival, refusing to be anyones punching bag or doormat.
Is it the right method to deal with conflict?
Well, thats open for debate.
She refuses to be taken for a fool by any of her classmates at North Shore.
Resultantly, she gets labeled the bully or the toxic one because she doesnt back down.
Do not test her patience.
