look up any word, like donkey punch:
 
1.
A combination of words "obviously" and "of course". Usually used when one is sure of a given event/thing to happen and/or finds it obvious.

The prefix 'of' in 'of course' is often skipped by the British, resulting in "'Course".
As "obviously" is shortened to "obv" almost exlusively in Internet/text speak, the term "obvcourse" is rarely utilised when speaking IRL.
John: Are we going to the park tomorrow morning?
Mike: Obvcourse, who would miss those birds!
