a creature from the depths of hell that shan't be trifled with. It is a reincarnation of satan himself with 8 legs and 8 eyes. He can smell your fear, he can smell your soul. If one comes into contact with said beast. Respond by running away and setting the area around it on fire.
The most useless creatures on earth. They are eight legged freaks whose only purpose on this earth are to terrify the piss out of humans so much that they had to name a phobia after it... ARACHNOPHOBIA.

The act of keeping your dick hard when in the process of masturbating (burning one off). Accomplished by cupping your hand and letting your fingers hang resembling that of a spider and stroking the head up and down with your fingertips. AKA The Spider

When a guy sticks his thumb up a girl's ass from behind (likely while fucking her doggy style) and lets his fingers rest on her upper ass/lower back (possibly tapping his fingers making it even weirder).

Jen: Fuckin amateur, lets make out.
