The process of taking an online shopping order to the brink of completion in order to get information about shipping cost etc, which the website will not otherwise give.
Dammit! I was edging a £500 order the day before payday, and accidentally completed the transaction.
When you're at the edge of reaching climax/orgasm in bed
"And if my body had a say/ I would come again/ Scared of what I might say/ Cause I'm at the Edge..." - "Body Say" lyrics hinting at edging sung by Demi Lovato
When you feel like you are about to reach an orgasm but the alcohol you drank beforehand says just kidding. Leaves you with an extremely frustrated feeling.
Got drunk with this girl last night and just ended up edging.
