A mixture of Cum and Snot, usualy contained within an absorbent material such as a Kleenex, produced by a
man ejaculating into the same absorbent material as he recently blew his nose into while enduring a heavy cold. The mixing of Cum and Snot can, in certain
hot humid conditions, release a harmless
gas and so produce a cumbubble

John into his Kleenex seconds before he ejaculated into the very same tissue and soon the hoped for cumbubble appeared,
