Yup. Whatsapp... XD It was a lack-of-autocorrect-FAIL! XD
I wanted to send to my teacher(who was on a trip to London with us and he told us to whatsapp him whenever we were late); we'll be there in a sec. What came out? ; "we'll be there in a sex" his reply; "as long as it's selamat, peti deposit keselamatan it's none of my business" XD I felt so embarrassed I hadn't looked at him for a bulan XD
