contradicktion/contradicktory
Where a dude claims to just like how a gal looks overall and/or just want a platonic friendship, but his massive bulging hard-on sends a totally different message.
Well-hung dude: I used to unintentionally scare off the ladies with my major contradicktion/contradicktory crotch-appearance until I learned to "relieve the pressure" just shortly before I went to meet the gal, so that Lulu would be too limp and exhausted to "jump to attention" at the first sight of the "luscious looker".
