okay, so I saw this film back in 2007/2008, possibly on the Horror Channel where all the awful cheap ones are shown. It was a woman who maybe took some poison or became part alien.. she was attractive and had a massive alien tongue which she used to kill men, one being a Pizza Delivery Guy and a guy in a club by kissing and suffocating him. im sure at one point she was in a park and rubbed her back on a tree.. she also at one point took over her male neighbors body and slept with his girlfriend. Very strange sounding but trying to find it for my best friends birthday (we watched it when we were 15 and thought it was hilarious) I’m sure it was American and in colour and I didn’t recognise any actors.
