When an offensive, harsh or blunt expression is replaced with an mild, indirect or vague one. 

Visual euphemisms exist, too, such as the one used for [[Akiyama Mio]]'s accidental [[pantyshot]] in the [[K-On!]] anime (a stripped bowl of rice) or when [[swastika]] or the [[hammer and sickle]] are replaced with more innocuous symbols to avoid offending the audience and/or so the work won't run afoul of laws banning the public display of either symbols.

An orthographic euphemism is spelling a word deliberately wrong (e.g. "porn" becomes "pr0n", "n0rp" or "prawn") to circumvent censorship algorithms on the usenet, websites, social media apps, etc.
