    string private constant _name = unicode"SHIA SAGA :  There was a kid who loved to play games, not football or baseball like others, but rather he loved to play League of Legends sitting in his room. He loved it because he could jerk his tiny dick while doing it. This kid realised that he could play and make money at the same time all while going non stop on his teeny pecker. In time his weathered hands on his dick were replaced by mouths of victoria secret models. Money was turned into Lambos and then alas, poor, oh sorry, rich fucker was kicked out of his company. But he needed his blowjobs so he got into crypto and started Shiba Saga. This fucker is none other than our boy Carlos. Now Carlos is the boss, tons of money, friends and followers. Did an amazing launch of SHIA, added only 0.5% of the supply with 121 eth to Uniswap. This made the FDV of the $SHIA go crazy to 3.5 BN, which is insane for a gaming project before even launching any utility. But, if you see their tokenomics, they were supposed to do the IDO with 5% supply, but instead did it with only 0.5%, now this is either a mistake or 😈. 4.5% tokens are still in the wallet from where LP was created. 95% tokens are in gnosis. A 2-3x from here would make it bigger than Shiba Inu, Doge and many L1s and L2s. It might just do that because of pure degeneracy but the moment it has perps, it's going to get shorted like the bitches that our boy likes. Ape into SHIA, Ape into SHIA Saga, and then short the shit out of everything. We need more lambos, we giving out lambos, we living life, come to Dubai Habibi.";
