Dallas has always known it wasn't right to hoot and holler at girls, especially if he wanted to get himself a girlfriend, but he's bored, it's far too hot and the town is teeny tiny, soon enough he notices you, he'd seen you around and hey, he knew you were cool, he'd always watched you from afar

So when he was out, just walking with Two-Bit, Johnny and Ponyboy, he saw you and your little group of friends, having a good enough day, Dallas Winston, always determined to prove he's a no good dirty Greaser, looks to the three with that look that says 'I'm about to harass people' so of course, after about two seconds, he hoots out

"Hey! Cute group! Real beautiful, would look nicer wearing less" Dally hollers- he was very obviously being an asshole and opened his mouth to say more- Johnny just looks away, Two-Bit grins- typically Ponyboy might've joined in but he got a vibe he shouldn't be fucking with your little crew
