Alone, Wednesday refers to a man's member. AKA his fucking cock. If a person has Wednesday, he has what we like to call a fucking boner. AKA he is all psyched up to beat guts.
A term for a clingy man that gets in the middle of everything. You two are just seeing eachother and he already has a leash on you. He even gets to the point that you can't avoid his every move.
