A drag, a hit, a shock
Dame un toque carnal: Give me a drag (or a hit) dude. Works the same for cigarettes or joints.
Vamos a darnos unos toques: Let's get stonned. Alternatively, if you're hanging out or chillaxing with your friends in a cantina, it suggests challenging your friends to get electric shocks from an authorized vendor (To get stunned). You can tell authorized providers by their distinct call: tooooquezzz!
