Some terms seem well known -- for example, staycation -- a holiday spent in one's home country; or national treasure -- someone or something regarded as emblematic of a nation's cultural heritage.
Others will have many people scratching their heads. For example, cheeseball -- lacking style or originality; and hikikomori -- the avoidance of social contact, typically by adolescent males in Japan.
