Is it that card game where players try to catch other players placing cards different to what they declare?
In that case, we call it "Bullshit".
Nah, different games, haha
Shithead is the game where you try to get rid of all your cards. I'll try to explain the rules.
You need to get rid of all your cards. You go clockwise or anticlockwise, each person placing a card down on the pile. You can only place a card of equal or higher value to the one placed prior. In ascending order, the values are 3, 4, 5, 6, 7, 8, 9, J, Q, K, A. If you can't place a card down, you pick up the pile. Then you have your special cards. A 2 resets the pile. So you can place a 2 on any card, and it'll reset the value back to the lowest. A 10 clears the pile -- you put the pile to the side, and it is no longer in use for the game. The 10 is discarded as well. You then start a new pile. A Joker is whatever you wish for it to be. If there are 4 of any card in a row on the pile, it acts as a 10, and whoever placed the 4th card gets to discard the pile and start the new pile.
To start the game:
-You have three cards face down in front of everybody. You can't touch these.
-Place three cards face up (on top of those cards) in front of everybody. I'll get back to these
-Give everybody five cards
-You can swap around any card from your face-up cards with your 5-in-hand cards. You'll want to do this strategically (your highest cards + special cards) as once you have no more cards in hand/in the deck, you have to use your cards facing up. If not, pick up.
-Once you've set all your cards, the person with the lowest value card places one down first. They then pick up one from the remaining deck. While the deck is still there, you must always have 5 cards in your hand.
-Once the deck is gone+5 cards in hand are gone, you can start with the face-up cards.
-After that, you have to use your three face-down cards. This is purely luck, and this is where salt rises.
-First to clear their cards wins.
-Keep playing until the last person. The last person is the shithead.
Hope that makes sense / rings any bells.
