Language: Tagalog
A playful expression of kilig (flustered excitement), paired with an elbow gesture. It loses all power (and kilig credit) if the siko motion is not performed.
“Tara Shoppee, Sha pipi ko ihhhhhh TITO KASE IHH *siko*”
Translation: Let's go Shoppee, in my pipi, Ihhhhhh, TITO, IHH *elbow*
