Musings from my 6 year old son

My son has the "sonar" hearing of a bat, so if there was ever anything we did not want him to pick up on, we would S-P-E-L-L it out like a dog and the V-E-T unfortunately he can spell, so that's that.
Somehow he heard the word "Bint" for an older lady.
He knows older ladies like "Vintage" so........................................
With much cackling he coined "Bintage" a chip off the old block no?
