Feels weird grabbing one personal photo (6)
I believe the answer is:
selfie
'personal photo' is the definition.
(a photo of one's self)
'feels weird grabbing one' is the wordplay.
'weird' is an anagram indicator.
'grabbing' means one lot of letters goes inside another.
'one' becomes 'i' (Roman numeral).
'feels' is an anagram of 'selfe'.
'selfe' placed around 'i' is 'SELFIE'.
(Other definitions for selfie that I've seen before include "Personal photo" , "21 [PHOTO]" .)
