Lawl is "Lol" usually the way it is pronouced. I use this word when I want to say Lol, except I'm not litterally laughing out loud, thus giving the word more importance.

1. Often used as an alternate spelling of lol. Mainly used by hipsters and rebels, however snotty 12 year-old's also like to spam this as well.
2. The true meaning unknown to the world is Laughing A Whole Lot. Used when 'lol' & 'LOL' don't describe the laughter enough. Not quite to the level of lmfao or rofl.
