-noun
1. A term that has come to describe GAINAX's often exaggerated animation of female characters' bouncing breasts. The term has its roots in Gunbuster (Top wo Nerae!), GAINAX's first OVA(1988) with an otaku-focused demographic, in which gainax bounce is found unabated in the three female characters of Noriko, Kazumi, and Jung. Utilization of gainax bounce can still be seen in GAINAX's works, partially as self-reference and self-homage and partially for pure fanservice.
2. Fanservice as it pertains to anime produced by GAINAX, primarily focused on female mammaries.

You start out on a bouncy object, such as a couch or trampoline. The girl then puts her ankles behind her ears, and the guy positions himself inside, and begins to bounce her (much like dribbling a basketball). Repeat until climax. Minimal effort is required for maximum speed.

To attack or greet someone with a protuberance of stomach. Must be pre-announced with a shout of "BELLY BOUNCE!" and to be truly authentic, be answered post-BB with the sweet slinkiness of a "Ling-Long-Ling...". Originating from the Russell Brand Podcast March 2015. Adopted by MMAS. Never a replacement for Pin-Pinnery.
