Soyjoy is the momentary europhoria felt by a soyboy when he has his routine injection of soy into his ass with a butt plunger.

Soyjoy is also the feeling a soyboy gets when he is gifted a nintendo switch from his wife for accepting her new boyfriend into the family.
Oh man, I can't hide the soyjoy that I am feeling after my recent top up.
Ahh son, look at this old family portrait of mine, you can just see the soyjoy on my face after I got that nintendo switch from your mother and real dad
