Picture quality is not great but it is not grass, it looks like a Sand Burr.

We've always had these in the lawn and I've never been stuck by a sandspur here. Anyways I'm starting to think it's bermuda grass but I'm having trouble finding any pictures of these sandspur-like things googling bermuda grass.

If the hand was held a little lower you'd see it is part of a grass

OK.. got it.. it's centipede grass :)

ah oops

I saw one in google images from centipede grass seed head but it was showing an image from a page on Globe Hedge.

Welp. I think this makes up the majority of our lawn.

Sorry for triple post

Looks like an immature seed head for false green kyllinga.

Does it have a triangular shaped stem cross section? I believe it is a sedge and should respond to something like Sedgehammer.

yeah dchall, it's definitely sedge

it grows a lot faster than the grass and it has the triangular blades

thanks for the tip on the sedgehammer, I was reading that this stuff is a real hassle to get rid of
