I happened upon a DeLorean today, took it up to the right speed and checked out 5e.
It's delivered as a perfumed spray and - the really important bit you've all been waiting for - the dispensing mechanism doesn't harm the ozone layer.
One or two or you may question the choice of a spray, but it's inexpensive, convenient and can substitute as a present for your girlfriend in times of emergency.
I know . . . I was scared too. How it might react with deodorants was an issue, but by the time I'd stopped complaining I'd clean forgot to get round to using it anyway
