Lalochesia is the state of sensual relief perceived in the use of vulgar language. This most satisfying feeling accompanies the act of telling someone to fuck off, to go fuck yourself, dispelling the stress of the moment. When you curse, if somebody reprimands your foul mouth, counteract her or his unimaginative ridicule by explaining that if it were not for lalochesia, rage would likely overwhelm, sponsoring the rearrangement of the features of either the room or the face, as appropriate. Defiance is very often an act of intelligence; that, and a modicum of humour, may diminish somewhat the discontent. If that does not work, though, no worries, just because one is offended, does not mean that one is right.
