Bit of a weird one really. My real name is Gabriel. Through an awful long development of convoluted derivations it got to Geebs. Probably due to a mispronunciation.
Someone decided they'd call me Jibrial one day. (Read it phonetically.) That was abbreviated to Jibs. That kinda sucked so I insisted that they got rid of that one. The vowel was lengthened and thus my name evolved. Geebs. Pronounced like Jeeves but with a 'b.' No idea how many people started pronouncing it with a hard 'G' when they first read it.
Geebs is what my friends call me so call me Geebs :D
