There's a saying in English that when someone can't let their horniness out for a while or if they get cock blocked they've been "blue balled". This is a saying because sometimes when a guy gets hard and isn't able to cum his balls will turn blue because he needs to cum so bad. Hope this helps! You can probably get a better definition if you look it up on Urban Dictionary
I've most commonly heard it used when someone hooks up with a guy but backs out before he cums, "she/he blue balled him"
Oh so kinda like if he like turns him on and jerks him off then suddenly stopped jerking him off before he could even cum?
Yeah, basically! If a guy actually gets blue balls it legitimately hurts, but I've most commonly heard it as a saying and haven't ever experienced a guy actually getting blue balls lol
