look up any word, like the eiffel tower:
When someone calls your mobile phone wanting you to call them back. Just let it ring twice so giving little oppotunity to answer it. This is useful if A. you're tight and do not want to use up your credit; and B. you have run out of credit.
hey honey, did you two bells me?
