look up any word, like bye felicia:
 
1.
IJJ
I Just Jizzed; used during the act of cybersex to inform the partner that one has just ejaculated. May also be used in conversation to relate a particularly arousing experience, such as seeing a loved one naked, or being fondled unexpectedly.
Chris: "Dude, IJJ!"
Barnes: "Me too!"
Both: "Small penis, up top!"
