noun
nuisance; obstructive person; troublesome person
Refers to a person who is in the way, bothersome, or a hindrance. Often used in casual, slightly negative contexts.

邪魔 is a broader term for hindrance or interruption, while 邪魔っけ specifically describes a person who is a nuisance.
Derived from 邪魔 (じゃま, hindrance) with the suffix っけ, which adds a sense of 'having the quality of' or 'tending to be'. The exact origin of っけ is uncertain, but it appears in colloquial formations.
