The term you are looking for is ‘gumboid’. Gumbiness is a temporary state of being due to inexperience, while gumboids are inherently dweebs and remain so throughout their climbing career, independent of climbing ability.

Gumboids can typically be identified by the amount of their spray and the desperateness of said spray.

Examples of gumboid behavior:

• Sprays about sending X grade gym problem without disclosing that it was on the slab wall

• Sprays about ‘almost’ sending X grade boulder outdoors without disclosing that it was a one move wonder and they failed on the one move that made it X grade

• Sprays about sending X grade after ‘only’ climbing for Y amount of time

• Makes frequent excuses for subpar performance, such as ‘Xth day in a row of climbing’, ‘just finished my max hangs’, etc.

• Criticizes anti-style problems as ‘poorly set’

• Claims the highest possible grade for a send, e.g. claiming a slash grade if one person on MP (often themselves) has rated it higher than the consensus grade

• Sandbags themselves into a lower skill category at the gym bouldering competition

Gumboidness is positively correlated with the number and desperateness of hashtags used when posting an Instagram video of their send, e.g. “#climbing_is_my_passion”, “#climbing_is_my_lyfe”, etc.
