I used to tell people after I got out that would ask me what I did when I was in, that I was a Ranger (a serious transgression to many battboys for which I now aplogize) but it was a lot less confusing than trying to quickly explain a LRSD to a civillian.
Finally a couple of Batt boys explained to me why they didnt like non batt boys calling themselves Rangers... I argued a bit about unit lineage, percentage of men that were tabbed, unit requrements and standards, etc... but I realized they were right. The only men (veterans and active) of the modern army that should be called Rangers are the men of the 75th.
