pretty, sexy" with the following added implications according to Mattiello: From the semantic point of view, slangy foxy is more loaded than neutral sexy in terms of information provided. That is, for young people foxy means having the quality of: (1) attracting interest, attention, affection, (2) causing desire, (3) excellent or admirable in appearance, and (4) sexually provocative, exciting, etc., whereas sexy only refers to the quality indicated in point (4). "shagadelic" is a combination of a slang term with a slang suffix and therefore is considered an "extra-grammatical" creation. Matiello stresses that those agents who identify themselves as "young men" have "genuinely coined" these terms and choose to use them over "canonical" terms —like beautiful or sexy—because of the indexicalized social identifications the former convey. First and second order indexicality In terms of first and second order indexicality, the usage of speaker-oriented terms by male adolescents indicated their membership to their age group, to reinforce connection to their peer group, and to exclude outsiders. Higher-order indexicality In terms of higher order indexicality, anyone using these terms may desire to appear fresher, undoubtedly more playful, faddish, and colourful than someone who employs the standard English term "beautiful". This appearance relies heavily on the hearer's third-order understanding of the term's associated social nuances and presupposed use-cases. Subculture associations Often, distinct subcultures will create slang that members will use in order to associate themselves with the group, or to delineate outsiders. Slang terms are often known only within a clique or ingroup. For example, Leet ("Leetspeak" or "1337") was originally popular only among certain internet subcultures such as software crackers and online video gamers. During the 1990s, and into the early 21st century, however, Leet became increasingly commonplace on the internet, and it has spread outside internet-based communication and into spoken languages. Other types of slang include SMS language used on mobile phones, and "chatspeak", (e.g., "LOL", an acronym meaning "laughing out loud" or "laugh out loud" or ROFL, "rolling on the floor laughing"), which are widely used in instant messaging on the internet. As subcultures are often forms of counterculture, which is understood to oppose the norm, it follows that slang has come to be associated with counterculture. Social media and internet slang Slang is often adopted from social media as a sign of social awareness and shared knowledge of popular culture. This type known as internet slang has become prevalent
