Jimlish
(Noun) A cross between English and Chicagoese. It involves bastardizing commonly used words in a nonsensical matter. Frequently speakers of Jimlish will often try to defend their bastardization of the word to no avail. Examples include: southmore (instead of softmore), uge (instead of huge), ashphalt (instead of asphalt, and sammich (instead of sandwich).
I often find myself asking my grandfather to repeat himself because he is speaking Jimlish
