weak in the knees
What one says/feels after they had amazing sex and/or a splendid fap session, the feeling is so intense you can barely stand up, thus weak in the knees.
Example:
Guy "Dude, you all right? your legs are wobbling"
Dude "Yeah I'm all right, I just received the best blow job from my gf; made me weak in knees "
"Damn, I jizzed so hard last night my legs couldn't support me for the next 3 minutes."
"Damn, I banged my gf so hard last night I thought my knee caps would explode"
