Jellyfishing is a term used to describe a feeling experienced in two circumstances:

1) Post-coital jizz lingering in your vaginal passage following unprotected sex.
2) Whilst experiencing the heavier side of your menstrual cycle.

In both instances, usually when moving from a horizontal or seated position to standing, the squeezy 'splodge'-like feeling of each substance exiting the mouth of the vagina feels like that of a jellyfish squirming its way out.

*Note*: neither can be felt whilst a tampon is in use as this stems the requisite out-flow prior to its exit.
1) Can I borrow a pad? Jack and I banged 4 times last night and I'm seriously Jellyfishing today!

2) FYI, this period is a heavier one and I'm Jellyfishing so much right now.

When you finish having sex with a girl and realise post-coitus the condom has been left inside her. In a haze of panic and confusion you use your index and middle finger to fish it out in a semi-sensual style. What you end up pulling out should look like a shrivelled old jellyfish, hence the term "Jellyfishing".
When Matt realised his vigorous love making and oversized condom had resulted in the rubber slipping off, he kissed Lisa while jellyfishing.

He eventually came up with the goods and then prayed she was not pregnant for the next few months.
