An rather unpleasant smell originating from the penis, commonly know as the "bell end". Usually caused by a build up of smegma around the gland of the penis.
A right dirty bastard, not washing his cock on a daily basis.
E.g. A girl giving her boyfriend oral sex and says to him " your dick smells like cheese", an unsuspecting cheesy bell whiff occured.
A cheesey bellend is an everyday house hold item. It is often enjoyed as a warm snack for replenishing salts and proteins. Cheesey bellends are available at most retail outlets upon request for example asda or tesco.
Mmmmmm this cheesey bellend is real salty today, good job I worked out before eating this cheesey bellend so I get use of the protein.
