What is that smell? If you've got large gauge ear gauges, it's probably dead skin and buildup in your ear lobes.
Ear funk is common problem for those with stretched ears over 6 or 4 gauge. It comes from a build up of dead skin cells that are trapped on the inside of your plugs. The best ways to eliminate this problem is by either washing your plugs everyday in the shower, or to wear wooden plugs (which are porous and will naturally absorb the grossness of your dead skin cells).
