Short for "lachflash". Replaces "lol" or "lmao".
Makes any sentence sound less aggressive. U can use it whenever you're sad, mad, happy, emotional and many more.

If you find something extremely funny you write it in caps. You can also put more "f"'s at the and to show that you find id even funnier.
