If it's the smug version, it's not okay imo.
Otherwise, it's slightly eyebrow raising to me but ultimately fine depending on the context/audience. The original "feels good man" is timeless.
Here's Collige's Extremely Unofficial Guide to Identifying Pepes
Feels Good Man / Happy Pepe: Okay, this is the original we all know and love ✅
Sad Pepe / Feels Bad Man: Also okay, this predates the alt-right by a while ✅
Smug Pepe: Not okay, it's one degree off from the weird Groyper shit, plus no one else really uses it anymore ❌
Groyper: 100% alt-right, spawned from the smug version ❌
Clown Pepe: 100% alt-right, used by the same people as Groyper as well as Actual Nazi Nick Fuentes ❌
Angry Pepe: Extremely sus, associated with that ableist REEEE bullshit from /r9k/ ❌
This predates the alt-right stuff though, it's just general internet terribleness
Apu / Helper Pepe: Not instrinsically bad AFAIK, but this specific version and its variations started a lot more recently (2016) than the original Pepe and its variants
✅
Weird/"rare" Pepes: Extremely meta and also out of date. Do people even still post these?
