Friend
¡Ay, qué padre! ¿A dónde van?
eye, keh PAH-dreh! ah DOHN-deh vahn?
Oh, how cool! Where are you going?
'¡Qué padre!' is Mexican slang for 'how cool!' In other countries you might hear '¡Qué chévere!' or '¡Qué genial!'

'¿Te animas?' is a casual, encouraging way to ask 'are you in?' or 'are you up for it?'

Como a las ocho. Te mando la ubicación por WhatsApp.
KOH-moh ah lahs OH-choh. teh MAHN-doh lah oo-bee-kah-SYOHN por waht-SAHP.
Around eight. I'll send you the location on WhatsApp.
'Como a las ocho' — the 'como' softens the time to mean 'around' or 'about.' Sharing locations via WhatsApp is standard.
