DEX for memecoins?

So I don't do the memecoin thing very often; I'm a long time buy/hold/CDA boring guy. But occasionally I jump into something using only profits for a bit of gambling...I did great with Doge last run and had a couple of bumps with SHIB. Anyway I went in in a couple of random presales with eyes wide open as far as scam potential Etc. My question is, where do y'all buy/trade/find these flash-pan coins? For reference, I might have Retik and Pambo incoming but, aside from my home wallet, I'm not familiar with where these get traded/pumped/dumped and so on. Any advice welcome.
