After being reproved for doing so myself on SO yesterday. I realized that over the last couple of years the meaning of the expression OCD, seems to have deflated. Up to the point where people(read I) mostly associate it with pet peeves like the price of a fill up at a petrol station and the amount of litres, not both being round or misaligned street tiles.
It is obviously very useful since most of us can relate to this feeling to some degree. However, in a slightly more formal context like SE, this obviously is not an appropriate word to use since its trivialises a very serious affliction and therefore might be hurtful to people suffering from real OCD.
What would be a viable alternative in a context like this?
