A key smash is exactly that, a random smashing of the keyboard that conveys intense or overwhelming emotion that cannot be expressed through words. However, there is an art to this trade. For the perfect key smash, use the "Home Keys" on your keyboard; this includes the letters a,s,d,f,j,k,l,; as well as g and h. The typical start letters are "a" and "j" but any of the Home Keys can be used. Once you have perfected your key smash, you can begin throwing in letters from the other rows for a personal touch. It is a staple of the LGBT community and a versatile conversational tool.
