Armpit fetishism (also known as maschalagnia) is a partialism in which an individual is sexually attracted to armpits.

The attraction is mostly directed towards the strong pungent odor of the armpit. The odor of the armpit is the most powerful in the body, sufficiently powerful to act as a muscular stimulant even in the absence of any direct sexual association. Those who have a fetish for armpits often enjoy kissing, tasting, smelling their partner’s armpits during sexual foreplay. Sometimes they would require their partners not to shower or wash their armpits, which would cause the smell to become stronger than it normally is.
