self- deprecation definition
Self-deprecation is the act of reprimanding oneself by belittling, undervaluing, or disparaging oneself, or being excessively modest. It can be used in humor and tension release. Self-deprecation is often perceived as being a characteristic of certain nations, such as Great Britain, Ireland, Australia and New Zealand, where  blowing one's own trumpet  is frowned upon.
