Song i heard on kmel... idk the title!! Help?

At first when I heard the song, I thought it was by YG because it sounded kinda like Toot it & Boot it. But then as I searched it nothing came up! The lyrics go Lil mama go in, go in, go in, go in lil mama go in... or i think it goes like that because when he said in it sounded more like insh.. Help please!
