That awkward walk by you do when:
- you're meeting someone somewhere and you're not sure if they're there yet
- you're not sure if the place you're going is open yet
- you think you see someone you know and want to make sure before going up to them
- you're not sure if the lecture is for your subject
''You're late! Where were you?''
''I wasn't sure if you were here yet, I did a casual badger past the window but I couldn't see you!''
''Is the shop open yet?''
''Dunno, I'll do a casual badger and have a look''
