The PBBC logo is a derivation, and it stands for PENYA BARCELONISTA BERLÍN CULÉ E.V.
Official FC Barcelona Fan Club Berlin:
Here is the PBBC website in Germany:

The GFY kiddie club that has usurped the PBBC logo (couldn't even come up with anything original), is a weak attempt at imitating the old BP4L-style postings, however this GFY PBBC group shows little creativity or humor in their postings, so in the end, all that they accomplish is making themselves look silly with their cliquish juvenile posts (it's an inside joke that really isn't all that funny).
