From a song.
1) Used as a funny way of saying argh.
2) Used as a comeback to do with getting a boner.
3) Used whenever you want.
1) P1: "You left your bag on the bus."
P2: "Argh that makes me hard!"

2) P1: "Yo did you see how the wind lifted up that chicks skirt!?"
P2: "Yessssss shes HOT!"
P1: "Argh that makes me hard!"

3) P1: "Hmmm I'm really bored..."
P2: "Argh that makes me hard!"
