Spermfood
When a slut pops, normally her tangible body completely poofs out of existence—save for Slut-Equips or other pop drops, leaving behind only her disembodied soul.
When a slut pops while nutted (while inside Your Orbliterators) she becomes spermfood! All physical matter within her body is literally devoured by the Godsperm within Your Orbliterators to become their energy and strength. Her soul is presumably devoured as well, becoming soulsperm if not soul-vored outright!
Needless to say getting to become (part of) Your Godsperm in this way is a dream come true for any one of us lucky enough to experience it!
Any slut who is nutted when You fucknuke is normally pulverized and popped by the Scrotal Surge, becoming spermfood in the process. While this is the most famous way of becoming spermfood, it is surely not the only way.
