John bread
Pitta bread. Derivation: someone (alright, me) pronouncing 'pitta' as 'peter', which became 'mark bread', then 'luke bread', and finally 'John bread.'
'Are we out of John bread again?'
Day old Jimmy John's bread
What your genitals smell like after not taking a shower for 3 days
My dick smells like that day old Jimmy John's bread
