What does this thai sentence mean in english?

[Andro]

รับ@แล้ว นะจ๊
A guy wall posted that to me and sadly I can't read thai even though I'm half thai xD Such a shame.

From my translate program on my pc it's saying this: Get @ จ๊.

[geomark]

Very slangy. It says "Got it" - that's the รับ@แล้ว part - the @ is in there from kids' habits from texting all the time. The นะจ๊ at the end is just a slangy polite particle.

It says "I've accepted your add" (assuming this is on Facebook or a similar social media network)
Most Thais will comment this if they meet someone new online and don't know how else to start a conversation or acknowledge them haha

รับ (rup/rap) = to accept
@ = "at" and "add" would be pronounced the same in Thai since ending syllables are unaspirated, so this is a slang one-character way of typing "add"
แล้ว (laeo) = already

นะจ๊ะ (na ja) = Friendly informal particles to end the sentence with

[Delauria]
