What does it mean if a dude says that he can't control himself and walks away?

me and a dude (recently made friends with) were playing basketball in the dark gym of our school and he says “give me a second”, and proceeded to say under his breath, “i can’t control myself” i heard it obviously but i never asked about it. but dead ass does it mean what i think it means?
