Russian word "ботать" ['botatj] means hard working aimed at improving your knowledge and comprehending the subject under studying. The word "ботай" ['botaj] is the imperative of "ботать" and makes you study hard from the sunrise to the sunset (though most of students prefer a night time to a natural daya and it is that is called natural)))
You can enjoy the great picture "Botaj" by my roommate Michael Demidov (just click the link above). Who do you think is illustrated there??
