Enchina comes from the verb enchinar, which is used in the common phrase "se me enchina la piel" to mean "I get goosebumps". The literal meaning of enchinar is 'to make curly' or 'to curl'.
In the song, the artist sings, "La piel se me enchina cuando tu te arrimas" (I get goosebumps when you get close). It's an evocative word that describes the powerful physical and emotional reaction he has to his partner's affection, a feeling that literally makes his skin tingle and his hair stand on end.
"Con Tus Besos" (With Your Kisses) by Eslabon Armado is pure, head-over-heels romance in the Regional Mexican style. The singer is completely infatuated, admitting in the very first verse, "Me traes bien loco todo el día pensándote" (You have me crazy thinking about you all day). He uses Mexican slang like "neta" (honestly / for real) in "yo contigo neta sí me enamoré" (with you, for real, I fell in love) to show he is not playing games. He dreams of doing grand romantic gestures, like bringing a full live band ("llevarte Banda") right to her door, traveling the world together, or promising to bring down the moon for her.
Beyond big promises, what makes this track sweet is how he notices the everyday details. He loves that she looks gorgeous with or without makeup ("sin o con maquillaje") in simple casual clothes, without pretending to be someone else. He admits that when she gets close, his skin gets goosebumps ("la piel se me enchina"). By the end, the vibe shifts to an intimate night in: "Cierra las cortinas, prende unas velitas" (Close the curtains, light some little candles). He closes by dedicating the entire track ("esta rola", slang for "this tune" or "this song") straight to her with simple gratitude: "Mil gracias por tenerme en tu vida" (A thousand thanks for having me in your life).
