It is commonly referred to as a ‘short position’, though it is not ‘shorting the stock’. Equally, purchasing calls* is referred to as a ‘long position’ (as is holding the equity).
edit: smallmancontrov below pointed out that I wrote 'purchasing puts' was long, when I meant to write 'purchasing calls'
It’s all a matter of perspective I suppose, and of course I understand why you say this, but no professional options trader I’ve ever met would speak in these terms.
