Nicofiend
Someone who is addicted to nicotine and always fiends off of your vape or whoever's they can get their hands on. Often uses a sketchy modified wire (fiend wire, tweaker wire) to re-charge their disposable vapes instead of getting new ones.
Lol Jake is such a nicofiend, he always wants to hit my vape
