Spunch bob is a meme that just shows how much you're humor is broken
the meme is basically a random screenshot from spongebob with a caption containing broken english such as
"aw hell naw spunch bob is ded"
"aw hell naw spunch bob took 40 benadryls"
the meme origin comes from twitter user:@big_brody_6 who replied to a post with the first ever spunch bob image saying "Oh hell nah they all up on spunch bob shit"
