I dunno if this counts as "conversational style" or "grammar" but I think any of

"power-lifting skirt-chaser, like the other..."
"power-lifting skirt-chaser... like the other meatheads..."
"power-lifting skirt-chaser -- like the othe meatheads..."

would look better than the full stop while still giving a pause between ideas. Generally in dialogue I don't mind subordinate clauses hanging around but when your whole message box is short stocky sentences it sounds weird and forced. This is more a variety issue imo.

..........maybe i'm just a message box nerd though

While the grammar police are in town, "typical power-lifting skirt chaser, like those other..."
You could even drop the 'other', but that's up for interpretation.
