lossy adj. [Usenet] 1. Said of people, this indicates a poor memory, usually short-term. This usage is analogical to the same term applied to data compression and analysis. ?He's very lossy.? means that you can't rely on him to accurately remember recent experiences or conversations, or requests. Not to be confused with a ?loser?, which is a person who is in a continual state of lossiness, as in sense 2 (see below). 2. Said of an attitude or a situation, this indicates a general downturn in emotions, lack of success in attempted endeavors, etc. Eg, ?I'm having a lossy day today.? means that the speaker has ?lost? or is ?losing? in all of their activities, and that this is causing some increase in negative emotions.
The Free On-line Dictionary of Computing (30 December 2018):

lossy A term describing a data compression algorithm which actually reduces the amount of information in the data, rather than just the number of bits used to represent that information. The lost information is usually removed because it is subjectively less important to the quality of the data (usually an image or sound) or because it can be recovered reasonably by interpolation from the remaining data. MPEG and JPEG are examples of lossy compression techniques. Opposite: lossless. (1995-03-29)
