peanutbutter rag 

the towel used and reused to catch a man's genetic material (sperm), so he dosen't get it on his bed, body, dog, ect. (the name is derived from the distinctive scent that the towel has because of its repeated use without being cleaned).

Troll was bored so he got out his peanutbutter rag when he started to play, so he could catch his "fun".
