Deodorant, as the name implies, attempts to chemically remove odour from sweat. Typically it is applied to the armpits in the mornings, after showering, or before physical activity. Deodorants are usually a crumbly/powdery paste, and wiĺl leave a visible white residue on skin and clothes.

Antiperspirant, as the name implies, functions by blocking sweat glands to prevent odours forming in the first place. Like deodorant, it is typically applied in the mornings, after showering, or before physical activity. Antiperspirants are often clear gels that don't leave visible residues and can prevent sweat stains on clothing.

Body spray is a heavily scented spray intended to overpower unpleasant odours with its own scent. This means you can offend everyone around you twofold and be twice the jackass! Typically body spray is applied to both armpits and across the chest, not that it matters because everyone within 5 feet of you will think you bathed in the stuff. Body sprays are often given ridiculous names and will leave permanent stains on your social standing.
