Seatbelting 

A derivative of fingering; the act of tickling a female ‘down there’, during which both parties face the same way, with the female recipient backed up against the front side of the ‘sender’; the senders working arm extends over the shoulder of the recipient, thus securing the recipient in place, resembling the appearance of a buckled seatbelt.

“Bro, did you see Ollie seatbelting Cadhla’s little sister at Ana’s last night? Was he playing counting stars in her ear through his phone?”
“Yeah so sick. Isn’t she like 17 though?”
