A post-formed string of ejaculate suspended precariously in the air between two points.  Common examples include:

* Penis-to-mouth (post #434231)
* Penis-to-vagina (post #472576)
* Mouth-to-hand (post #287806)
* Offscreen (post #4293)

Other examples: post #183160, post #474315, post #299321

If the stream is free-hanging, tag as [[cumdrip]] instead.  If the stream is still in the process of being formed, tag as [[projectile_cum]] instead. Do not confuse with [[precum string]], which is clearer.
