A pornographic recording, mainly used in reference to pornography on a VCR tape.
Woman: "Stop watching that fucktape while we make love"
Man: "Maybe if we fucked instead of made love then I wouldn't have a need to watch the fucktape""
Fucktape, a derivative of Fucktard, its purpose while primarily derogatory will have the additional functionality of confusing and bewildering the victim. Best used out of the blue in a SMS message against an unsuspecting target for greatest impact.
