"SMWB", sometimes referred to as "#SMWB" is an acronym that can be used when blatant and extreme profanity may not be deemed acceptable within the current environment or situation.

"SMWB" is the acronymn for "Suck My Wrinkly Balls" and is a modern day variant of more traditional, sexually suggestive profanities such as "Suck My Dick"

The origins of "SMWB" or "#SMWB" can be traced back to the UK Start Up scene where entrepreneurial characters coined the phrase in an attempt to avoid upsetting new employs of a delicate nature or instigating the wrath of the newly founded HR department.

When in the presence of those of a delicate nature, and during any form of HR related Tribunal, the use of "SMWB" can be explained away with the non offensive "Shaking My Whole Body" whilst those other, more morally corrupt and thick skinned, members of the team can delight in it's true meaning with a hidden chuckle and a glorious mental image.

When you eat dirt for the first time and leave your family to build a shack in the woods

Shaking my whole body. A step higher than SMH(shaking my head).
