ATM

Online jargon, it’s an abbreviation used in texting, online chat, instant messaging, email, blogs, newsgroups and social media postings.

ATM also stands for "Asynchronous Transfer Mode" which is a very high-speed telecom transmission technology. It is a networking and communication protocol designed for the transfer of multimedia data. It is a high-bandwidth, low-delay packet-switching and multiplexing technique (based on a fixed-length 53-byte cell). All broadband transmissions (such as video, audio, and text) are divided into a series of cells and routed across an ATM network. The most significant feature of ATM is its uniform handling of services, allowing one network to meet the needs of many broadband services.

ATM also stands for "Automated Teller Machine" where you can get yuppie food coupons ;-)
