Lockdick 

The inability to reach orgasm after a lengthy pound session. (Not to be confused with drunkdick)

My girlfriend and I pounded for hours last night. I just couldn't finish off. Worst case of lockdick I've experienced.

The Lockpick 

When you are doing missionary, you insert your finger into her bum and can feel both your penis and the finger against each other to find the sweet-spot, like a lockpick.

I was doing missionary with Alissa the other night and did the lockpick. Gotta say, shit was tight.

Lockpicking 

The act of having sex with a chick and either her or you sticking 2 fingers inside her vagina at the same time as his dick; hence, it is like picking a lock.

Dude!! This chick I was fucking last night was totally 'lockpicking' herself but after a few minutes, I took over.

Size 8 Lockpick 

The act of kicking open a locked door or container with your boot.

I was trying to open the shipping container and realised it was locked. I then applied my Size 8 lockpick to remedy the situation. Job Done!

Lockpick 

The "Lockpick" is the act of putting glue on the penis and inserting it in a womens vagina. You wait 5 minutes then try your best to just yank it out as hard as you can often ending in blood, or severe cock and vagina irritation.

"Yo home dog, I just completely lockpicked my bitch last night man!"
