To falsely confess to downloading pornographic material to get the real culprit out of trouble.
Oh shit, I forgot to wipe my porn from my girlfriend's laptop!

Don't worry, I'll tell her it was me, I'll take a wank bullet for you buddy!

Get the wank bullet mug.
When you have watched porn on someones computer without their permission and they find out. Your friend takes the blame and says they have a wanking problem.
John: Fred I lent you my computer the over day and found a video of a gay gang bang.

Fred: It wasn't me.

Clive: It was my fault fred popped out for a coffee and I was watching it. I have a wanking disorder and I knock one out 12 times a day.

(John leaves)

Clive: I just took a wank bullet for you.
