When an object of saturation was so bountifully exquisite that just dubbing it bussin (with a lowercase b) would be a incontrovertible disservice to the bussin-in-question. Therefore, a capital B is mandated to stand before this statement as a prerequisite to a delicious specimen.
NOTE: a girl PMSing or having a bad day is just that. Bitch with a capital B is a girl (maybe even a guy) who is just always sour unless you kiss his/her ass.
The phrase 'Itch With A Capital B' is often used to describe rude, offensive and annoying, normally quite popular, teenage girls. The phrase is often shortened to 'Itch' which gives the user a sense of security. They can even say, within earshot of the 'Itch With A Capital B', that she feels 'Itchy' around said 'Itch With A Capital B'. The phrase may be shortened even further to simply 'I'. The phrase is referring to, subtly, to a Bitch. It's a kinder phrase and whilst the 'Itch' works out what it means, it gives the user a head start to escape.
One may use the phrase in such examples:
"That girl is such an Itch With A Capital B!"
"That Itch over there, she just offended my brother, I heard her!"
"We, the non-popular girls are sticking together against them evil Is!"
A non-capital battlecruiser arrangement is a paradoxical or contradictory term which essentially defines names and words that sound like they're real together, but are actually not.
