gigg'n 

To dance real hard; or to dance a lot. To get your groove on.

We went to the club last night and we was gigg'n hella hard.

Giggna 

The safest way for a white man to say the word 'nigga'.

White Kid1: Well... they can't get mad if we say... giggna... right?
White Kid2: Damn right, giggna! Break yo'self giggna! What up my giggna?!
