Tushie (Two she), Squooshy (Skwu-she), and Gushy (goo she) is an endearing term used for those who received spunk in their ass and now said spunk is leaking out of their asshole. Equally used between gay men and women who enjoy anal sex. The term is a loving way of saying, "I enjoy your cum shot in my rectum."
Person 1 - I love you, Bruce!
Person 2 - I love my Tushie Squooshy Gushy, John.
(They then kiss with tongue)
Daughter - I love Jamal! He gives me the Tushie Squooshy Gushy all the time!
Mom - If only I could have been so lucky instead of you being conceived.
