How do I get a big muscular butt? Squats and deads haven't helped much

At the top of your deadlift, flex your glutes.
you get a godly pump which makes your ass plump and firm.
Just be prepared to be butthurt in the next 1-2 days.

Strong and weak points are genetics. If OP's glutes are a weak point, then he can always focus more on them to bring a bit more balance but the will never be a strong point.

Elliot plz go.

summer please leave... stop being a dipshit

Strong butts only work on GODLY narrow hips.

If you have average hips or beyond, forget about it.
