In the NT (KJV) we find the word chrisma translated into English as "anointing" twice and "unction" once, all in 1 John, and referring to Christians in general. And the word chrio is only used five times and is translated "anointed", referring four times to Christ and once to believers in general. So in the NT the anointing is used individually only of Christ (the Anointed One), and generally of all Christians- we are all "anointed".
So perhaps pentecostal/charismatic types are using the term esoterically to refer to being gifted....or what? Perhaps some bros or sisters can enlighten me.
