A Trouser 

A pervy old guy with smelly unwashed suspicious looking trousers who creeps you out and you can smell a mile away. Best avoided at all costs especially if he leers at you or plays with his pocket billiards. The reaction to the Trouser is usually a strong gag reflex.

Watch out, there's a trouser totally checking out your ass!!

pitch a trouser tent 

to sport a woody that is second to none;
the hardest, stiffest penile erection on the face of the planet; to pack more wood in one's trousers than a lumber yard; a raging hard on that sports more veins than an 80-yea-old woman's hamhocks.

When I saw her crunchy frogs and curvaceous can, Willy The One Eyed Wonder Worm pitched quite the trouser tent!
