Slipping seat post
My seat post won't stay were I fucking leave it. I was out riding and noticed it had slipped down about an inch so I lifted it back to where I wanted it. A little while later it was down again so I tightened the bolt on the QR clamp and proceeded to bust the clamp lever. Fuck. So I mashed it closed with a rock and rode on. I stole a lever/bolt from a clamp I had laying around at home and replaced it. I tightened it and the post slipped, I tightened it more, and the post slipped, I tightened the nut with a pair of pliers then closed the QR. And the post slipped. I've got this fucker as tight as possible and it keeps slipping.
Any suggestions for keeping the post were I want it? Throw some sand in the seat tube?You are what you eat.

1) it IS the correct size?
2) clean post of most of lube, and very fine grit sand on the post

is there any grease on the seat post?
if no, put some on there
(unless it's carbon, then find the fancy special sauce for it)

I've used a small section of beer can as a shim to prevent slipping in a similar situation.

I had this problem with my hard tail, and I resolved it by putting a little grease on the quick release which made it so I could get it a little tighter.

What material frame? What material post?
If it's a carbon post and carbon frame, you'll want some carbon paste... sure it costs like $5, but your bike probably wasn't that cheap, so just do it right. Apparently toothpaste works...
If it's a carbon frame and an aluminum post, go get a carbon post, then see above comment... or else you'll have bigger problems.
If it's aluminum on aluminum... any ghetto method works.

Install a dropper and use that variable height to your advantage?
DISCLAIMER: I have yet to get a dropper myself

On my aluminum trail bike I've had great luck rubbing the slipping seat post with chalk before clamping.
That Don't Make No Sense

Try a bolt thru seatpost collar, it will hold tighter than a QR one. Also use friction paste instead of grease.

It's a giant Reign. Aluminium frame with stock dropper. I'm going to change the clamp for a bolted one and chalk the post.

If you read ADKMike's new bike thread, you'll see this topic addressed, Beaver.
Remove post, clean seat tube & dropper post outer with rag & alcohol. Apply thin coat of carbon paste to seat tube & to dropper post outer tube. The carbon paste will prevent slide/twist issues. I'll bet you don't even need the lowest acceptable torque on the seat clamp to prevent post drop/twist. You use a torque wrench, right?
Also, don't descend while in the saddle!

Don't decent while in the saddle? How's that going to work? I take my feet off the pedals, stick my legs out and go "Wheeeeeee" all the way down.

That may work. Remember, "style" is key. Hence, I assume, Danno's post.
I was thinking back to late 90s/early 00s, as I often do these days with "plus" and "extra wide" tires etc.
People used to bend saddles, have slippy posts, etc because in that Shore-inspired era, they rode little "drops" sitting down. And unrelated to Shore-ness, I've known a few people who bent saddle rails because they descend sitting.
Obviously if you post on TGR and aren't stuckie, you know to stand up.

I just used some of that paste for carbon frames to quiet my creaky seat post, I bet that stuff would work on aluminium too
