Fuck Yeah (sometimes called "Close Enough") is a series of four-pane cartoon strips featuring a stick figure looking rather self-complacent and quite frankly, for all the right reasons. Originally posted via /b/ board on February 11, 2010, these cartoons illustrate all sorts of triumphant moments in our daily lives that make us feel awesome, like when you wake up a few seconds before the morning alarm goes off. This phenomenon can be also seen as the antithesis to Rageguy comics, another four-pane series originating from 4chan circa late 2008. This meme shares some similarities with the advice animal Success Kid.
Like A Boss Is a term occasionally associated with the Fuck Yeah guy that also implies that someone does something really well. This name is also sometimes used instead of Fuck Yeah for people who don't like to use offensive language.
