Giggl/ing/es/ed Like a Bitch: The point in which you forgo your normal laughing technique, which can range anywhere from a hearty chuckle to a light, airy, almost bell-like giggle, to a more, high pitched, uncontrollable, extremely obnoxious explosion of pent up comedic energy. A Laugh-splosion if you will. Now, if the Laugh-splosion is near atomic level, then we must add another L to the mix. so if you shit yourself during this Laugh-splosion, we would say you GLLB. Giggled Like a Little Bitch. Very similar to Rofl and Roflmao.
"Hey Brah! remember that time that hilarious shit happened and you GLB and fell on the floor?" (Giggled like a bitch)
